Introduction

With the rapid development of the manufacturing industry, 

die-casting machines play an increasingly important role

in metal casting. As an efficient molding process, 

die-casting machines, as important metal molding

equipment in industrial production, can quickly produce

metal parts of complex shapes. The safety and convenience 

of their operation have always attracted much attention. 

In this process, steel grating handrails, as a common protective

and auxiliary devices, play an indispensable role in the 

field of die-casting machines. This article will explore in

depth of the application of steel grating handrails in die-casting

machines, including their functions, characteristics, installation

methods, and their importance to the overall operation of 

die-casting machines and the safety of operators.

Overview of die-casting machines

1. Working principle of die-casting machines

Die-casting machines are equipment that quickly injects

liquid or semi-liquid metal into the mold cavity under

high pressure to solidify and form it, thereby obtaining

precision castings. 

It is mainly composed of a clamping mechanism, an injection

mechanism, a hydraulic system, an electrical control system,

and other parts. During the working process, the clamping

mechanism first closes the mold, and then the injection

mechanism injects the molten metal into the mold cavity at

high speed and high pressure.After pressure maintenance and

cooling, the mold is opened and the molded casting is taken 

out.

2. Application fields of die-casting machines

Die-casting machines are widely used in many industries 

such as automobile manufacturing, aerospace, electronic 

communications, and machinery manufacturing. For example, 

automobile engine cylinders, gearbox housings, wheels and 

other parts, as well as the shells of electronic products

such as mobile phones and computers can be produced by 

die-casting machines. 

Since the die-casting process can produce castings with 

complex shapes, high dimensional accuracy, and good surface

quality, it occupies an important position in modern 

industrial production.

3. Safety risks of die-casting machines

Although the die-casting machine has efficient production 

capacity, there are certain safety risks during operation. 

High-temperature molten metal, high-speed injection parts,

and strong clamping force may cause harm to the operator. 

In addition, the working environment around the die-casting

machine is usually more complicated, and there are potential

dangers such as slipping and tripping. Therefore, taking 

effective safety protection measures are crucial to ensure 

the normal operation of the die-casting machine and the life

safety of the operator.

Features and advantages of steel grating handrail 

design

The design of steel grating handrails usually adopts a 

modular structure, so that it can be flexibly adjusted 

according to different types of die-casting machines. 

During the design process, the following aspects should

be considered:

1. Ergonomics: The height, width, and inclination of the 

handrail should conform to the principles of ergonomics

to ensure that workers maintain a comfortable posture

during long-term operation.

2. High strength and durability

The selection of steel is crucial. High-quality steel 

can not only withstand heavy weight but also resist 

high temperature and corrosion, and extend its service 

life. The steel grating handrail is made of high-quality

steel, with high strength and hardness, and can withstand

large external impact. 

In the working environment of the die-casting machine,

it is often subject to vibration, collision, and operator's

leaning during equipment operation.The high-strength 

characteristics of the steel grating handrail ensure 

that it can play a long-term and stable role, is not 

easy to deform or damage, and prolongs its service life

and reduces maintenance costs.

3. Good anti-slip performance

The working area around the die-casting machine may have

oil stains, metal chips, and other debris, which can 

easily cause the ground to be slippery and increase the

risk of operators slipping. The surface of the steel 

grating handrail is usually specially treated with good

anti-slip properties.

Even in a wet or greasy environment, the operator can 

firmly hold the handrail to ensure the safety of walking

and operation. This anti-slip property is of great 

significance to improving the overall safety of the 

die-casting machine workplace.

4. Ventilation and light transmittance

Compared with solid handrail materials, the steel grating

handrail has unique ventilation and light transmittance.

Its structural design allows air to circulate freely,

reduces the accumulation of dust and moisture, and helps

to keep the environment around the die-casting machine 

dry and clean. 

At the same time, good light transmittance also makes 

it convenient for operators to observe the operation 

of the equipment, detect abnormalities in time, and take

corresponding measures. This ventilation and light 

transmittance not only improves the quality of the working

environment, but also provides convenience for the 

maintenance and management of the equipment.

5. Beauty and modernity

Modern industrial equipment not only focuses on 

functionality, but also appearance design has become 

increasingly important. The design of the steel grating

handrail should be coordinated with the overall style 

of the die-casting machine to enhance the overall beauty

of the production environment.

The appearance of the steel grating handrail is simple 

and generous, with smooth lines, and has a certain sense 

of modernity and industrial beauty. It can be integrated 

with various types of die-casting machines and the overall

style of the workplace, improving the overall image of the

work area. While focusing on production efficiency, it also

creates a comfortable and beautiful working environment for

operators, which helps to improve employees' work enthusiasm

and job satisfaction.

6. Easy to install and maintain

The installation of the steel grating handrail is relatively

simple, and it can usually be customized and installed 

according to the actual layout and operation requirements 

of the die-casting machine. It can be fixed in a suitable 

position by welding, bolting, etc. The installation process

is fast and efficient, and will not cause too much interference

to the normal production of the die-casting machine. 

In terms of maintenance, the steel grating handrail only needs

to be cleaned and inspected regularly. If damaged or deformed 

parts are found, they can be replaced in time. Its simple 

maintenance method reduces maintenance costs and maintenance

difficulties, ensuring that the handrail is always in good

working condition.

Advantage Analysis

1. Improve safety

The operating environment of the die-casting machine is 

usually more complex, and workers face a variety of potential 

dangers. The steel grating handrail provides workers with 

a reliable support point, which helps to avoid falls and 

other accidents.

2. Enhance work efficiency

By providing a stable operating platform, the steel grating

handrail helps workers work more effectively near the 

die-casting machine. Workers no longer need to be distracted 

by maintaining balance, so they can focus more on the task

at hand.

3. Easy to maintain

The material of the steel grating handrail is usually corrosion-resistant

and high-temperature-resistant steel, so it does not require

too much maintenance. This reduces the maintenance cost in 

long-term use and improves the economy of the equipment.

Specific application of steel grating handrails in 

die-casting machines

1. Operating platform handrails

The operating platform of the die-casting machine is the 

main area for operators to operate and monitor the equipment.

The steel grating handrails are set around the operating

platform to provide operators with safe walking and

standing space. The operator can hold the handrail at 

any time during the operation to maintain the balance and

stability of the body and prevent injuries due to accidental

falls.

For example, when the operator needs to adjust the parameters

of the die-casting machine, check the mold, or deal with 

some emergencies, the steel grating handrail can provide

reliable support and protection for it to ensure the smooth

operation.

2. Stair handrails

In the die-casting machine workshop, stairs are usually set 

up for operators to go up and down different working levels.

Stair handrails are important facilities to ensure the 

safety of people going up and down the stairs. Steel grating

handrails have many advantages as stair handrails. 

Its anti-slip performance can effectively prevent operators

from slipping when going up and down the stairs, especially 

when there may be oil or other debris on the surface of the

stairs.

At the same time, the strength and stability of the steel 

grating handrail can withstand the leaning and gripping force

of people when going up and down the stairs, ensuring the 

safe use of the stairs. In addition, the ventilation and light

transmittance of the steel grating handrail makes the stairwell

more bright and the air more circulated, reducing the erosion 

of the stair structure by the humid and dark environment, and

extending the service life of the stairs.

3. Equipment surrounding protective handrails

The surrounding areas of the die-casting machine, such as 

the mold installation area and the metal liquid pouring area,

have higher safety risks. Setting up steel grating handrails

in these areas can form an effective protective barrier to 

prevent operators from accidentally entering dangerous areas.

For example, during the mold installation process, the operator 

needs to perform a series of delicate operations next to the 

die-casting machine. 

If there is no isolation of the protective handrail, it may

be injured by accidentally approaching a moving part or 

high-temperature areas. The setting of steel grating handrails

can divide the safe area and the dangerous area, reminding 

operators to pay attention to safety, and at the same time

restricting irrelevant personnel from entering the dangerous

area, reducing the probability of accidents.

4. Material conveying channel handrails

During the die-casting production process, raw materials 

(such as metal ingots) and finished castings need to be conveyed.

The material-conveying channel is usually located around 

the die-casting machine and people walk around the channel 

frequently.

Setting steel grating handrails on both sides of the material

conveying channel can, on the one hand, provide safety protection

for operators when walking and to prevent collisions with

conveying equipment or materials; on the other hand, the

handrails can also play a guiding role, allowing personnel

to walk in an orderly manner in the channel, avoiding chaos

and congestion, and improving the efficiency and safety of

material conveying.

Installation points of steel grating handrails

1. Selection of installation position

When installing steel grating handrails, first of all, 

according to the layout and operation process of the die-casting

 machine, reasonably select the installation position of the 

handrail. Make sure that the handrail is installed in a place 

that is easy for operators to touch and need support, such as 

the edge of the operating platform, both sides of the stairs, 

and the boundary of the dangerous area around the equipment. 

At the same time, the convenience of the handrail should be 

taken into account to avoid the installation location affecting 

the normal operation of the operator and the maintenance and 

repair of the equipment. 

When choosing the installation location, it is also necessary 

to combine the actual situation on-site, such as space size,

light conditions, ventilation conditions, etc., to ensure that 

the handrail can play the best protective and auxiliary role.

2. Determination of installation height

The installation height of the steel grating handrail should

comply with ergonomic principles and relevant safety standards. 

Generally speaking, the height of the operating platform handrail

should be between 1.0 and 1.2 meters to ensure that the 

operator can easily hold the handrail when standing and walking.

The height of the stair handrail should be adjusted according 

to the slope of the stairs and the height of the user group, 

usually between 0.9 and 1.1 meters. For the equipment perimeter

protection handrail and the material conveying channel handrail,

the height should be determined according to the specific 

degree of danger and protection requirements, but generally 

should not be less than 1.0 meters. 

When determining the installation height, it is also necessary 

to consider possible special circumstances, such as the height

limit when the operator wears a safety helmet or carries a large

objects, to ensure that the handrail can provide effective 

protection for the operator in various situations.

3. Choice of fixing method

There are two main fixing methods for steel grating handrails:

welding and bolting. The welding fixing method has the advantages

of firm connection and good integrity, but it is not easy 

to disassemble and adjust after installation. It is suitable 

for permanent installation and occasions with high requirements

for handrail stability. 

The bolt connection method has the characteristics of a convenient

installation and disassembly, easy adjustment and replacement,

and is suitable for situations where the handrail needs to

be maintained frequently or adjusted according to changes in

production processes. In the actual installation process, 

the appropriate fixing method should be selected according

to the use environment and specific requirements of the 

die-casting machine. Regardless of the fixing method adopted,

the strength and reliability of the connection part must be 

ensured, and the fixing parts must be regularly checked 

for looseness and tightening in time to ensure the safe

use of the handrail.

4. Coordinated installation with other equipment

In the die-casting machine workshop, steel grating handrails 

often need to be installed in coordination with other equipment

and facilities. For example, on the operating platform, the 

handrails should be reasonably arranged with equipment such as

consoles and protective doors to avoid mutual interference. 

On the stairs, the handrails should be closely matched with 

the railings, steps, and other components of the stairs to 

ensure the safety and stability of the overall structure. 

Around the equipment, the installation of handrails should 

take into account the safe distance from the moving parts, 

pipes, cables, etc. of the die-casting machine to prevent 

the installation of handrails from affecting the normal 

operation of the equipment or causing other safety hazards.

Before installation, comprehensive planning and measurement

should be carried out on-site, and a detailed installation 

plan should be formulated to ensure that the steel grating 

handrails can work in coordination with other equipment and 

facilities to jointly protect the operation of

the die-casting machine and the safety of operators.

Maintenance and care of steel grating handrails

1. Daily cleaning

Regular cleaning of steel grating handrails is an important

measure to maintain their good performance and appearance.

Since there may be oil, dust, metal chips, and other debris 

in the working environment of the die-casting machine, these 

substances are easy to adhere to the surface of the handrail,

affecting the anti-slip performance and aesthetics of the 

handrail. 

Therefore, the handrail should be cleaned every day 

or regularly with appropriate detergents and tools. For areas 

with heavy oil pollution, special oil cleaning agents can be 

used for cleaning, and then rinsed with clean water. During 

the cleaning process, be careful to avoid using sharp tools to

scratch the surface of the handrail to avoid damaging its 

protective coating and structure.

2. Inspection and maintenance

Periodically conduct a comprehensive inspection of the steel 

grating handrail to promptly detect and deal with potential

problems. The inspection content mainly includes the structural 

integrity of the handrail, the tightness of the connection parts,

the wear and corrosion of the surface, etc. If the handrail 

is found to be deformed, broken, loose or corroded, it should

be repaired or replaced in time. For minor deformation and 

damage, appropriate tools can be used for repair; for severely

damaged parts, new steel grating handrails must be replaced to 

ensure their safety performance. 

When repairing and replacing, they must be carried out in strict

accordance with relevant operating procedures and standards 

to ensure the quality of repair and the compatibility of

replacement parts.

3. Anti-corrosion treatment

To extend the service life of the steel grating handrail 

and prevent it from corrosion, corresponding anti-corrosion

measures should be taken according to the characteristics of

the working environment. If the air humidity in the die-casting

machine workshop is high or there is corrosive gas, the surface

of the handrail can be treated with an anti-corrosion coating, 

such as spraying anti-rust paint, galvanizing, etc. 

At the same time, it is necessary to pay attention to regular

inspection and maintenance of the anti-corrosion coating. 

If it is peeled off or damaged, it should be repainted in time. 

In addition, the corrosion risk of steel grating handrails can

be reduced by improving the ventilation conditions of the 

working environment and reducing the emission of corrosive substances.

4. Lubrication and maintenance

For some active connection parts, such as the connection between

the handrail and the bracket, rotating parts, etc., lubrication

and maintenance should be carried out regularly to reduce friction

and wear and ensure the flexible use of the handrail. Select a 

suitable lubricant and operate according to the prescribed lubrication

cycle and method. During the lubrication process, care should 

be taken to avoid lubricants from contaminating the handrail surface

and the surrounding environment to avoid affecting its anti-slip

performance and working reliability.
