Wire Cut Electrical Discharge Machining (WEDM) is a device that uses a moving thin metal wire as an electrode to cut metal through electric spark discharge.

2. Working Principle

The wire-cutting machine cuts the workpiece into the required shape and size through an electric spark discharge between the electrode wire and the workpiece.

The electrode wire moves continuously during the cutting process, thereby realizing the processing of complex shapes.

3. Application Scenarios

Wire-cutting machines are widely used in the manufacture of high-precision and complex-shaped mold parts, such as stamping molds and precision parts molds.

4. Importance

Wire-cutting machines can achieve high-precision cutting processing and are ideal for manufacturing complex-shaped molds.

Grinding Machine

1. Equipment Introduction

A grinding Machine is a device that removes material from the surface of a workpiece through grinding, which is used to improve the surface quality and dimensional 

accuracy of the workpiece.

2. Working Principle

The grinding machine contacts the workpiece surface with a high-speed rotating grinding wheel to perform grinding processing, remove excess material from the 

workpiece surface, and achieve a smooth and flat effect.

3. Application Scenarios

Grinding machines are widely used in the finishing stage of mold manufacturing to improve the surface finish and dimensional accuracy of the mold.

4. Importance

Grinding machines can significantly improve the surface quality and accuracy of the mold and are indispensable equipment in the mold manufacturing process.

Polishing Machine

1. Equipment Introduction

A polishing Machine is a device that performs finishing processing on the surface of a workpiece through a polishing medium to improve the surface finish and 

aesthetics of the workpiece.

2. Working Principle

The polishing machine removes tiny bumps and scratches on the surface of the workpiece through the friction between the polishing wheel or polishing cloth and the 

workpiece surface, thereby achieving a mirror effect.

3. Application Scenarios

Polishing machines are widely used in the final stage of mold manufacturing to improve the surface finish and aesthetics of the mold.

4. Importance

Polishing machines can significantly improve the surface quality and visual effect of the mold and are indispensable equipment in the mold manufacturing process.

Injection Mold Machine

1. Introduction to the Equipment

Injection Mold Machine is a device used to manufacture injection molds and is widely used in the production of plastic products.

2. Working Principle

The injection mold machine injects plastic raw materials into the mold cavity by heating and pressurizing and forms the required plastic products after cooling.

3. Application Scenarios

Injection mold machines are mainly used to produce molds for various plastic products, such as home appliance housings, automotive interiors, and electronic 

product housings.

4. Importance

Injection mold machines are key equipment for the production of plastic products and can achieve high-efficiency and high-quality production of plastic products.

Die Casting Mold Machine

1. Introduction to the Equipment

Die Casting Mold Machine is a device used to manufacture die-casting molds and is widely used in the production of metal products.

3. Working Principle

The die-casting mold machine injects molten metal into the mold cavity through high pressure and forms the required metal products after cooling.

Selection Guide for Mold-Making Machines

1. Select equipment according to demand

When selecting a mold-making machine, you should choose the appropriate equipment type and specifications according to production needs.

For example, for mold parts with high precision and complex shapes, you can choose CNC machining centers and wire-cutting machines; for the processing of hard 

materials, you can choose EDM machines.

2. Consider equipment performance

When selecting a mold-making machine, you should consider the processing accuracy, efficiency, and stability of the equipment. High-performance equipment can 

improve production efficiency and mold quality, and reduce processing time and cost.

3. Pay attention to brand reputation

Choosing a brand with a good reputation just like LK and after-sales service can ensure the quality and after-sales guarantee of the equipment. Before purchasing 

equipment, you can refer to the evaluation and suggestions of other users.

4. Comprehensive consideration of cost

When selecting a mold-making machine, you should comprehensively consider the purchase cost, operation cost, and maintenance cost of the equipment. Choosing 

equipment with high-cost performance can reduce the overall production cost.

Future development trends of molding machines

1. Intelligence

With the development of artificial intelligence and Internet of Things technology, molding machines will gradually become intelligent. Through data analysis and 

intelligent control, molding machines can achieve fully automated production and intelligent monitoring, improving production efficiency and product quality.

2. High precision

Future molding machines will have higher processing accuracy and can produce more precise molds and products. High-precision equipment can meet the ever-increasing 

product quality requirements and enhance market competitiveness.

3. Multifunctionality

Molding machines will develop in the direction of multifunctionality, and one device can complete many different types of mold manufacturing tasks. For example, 

the future CNC machining center may have multiple functions such as milling, drilling, boring and tapping at the same time to meet the processing needs of complex 

molds.

Green and environmental protection

With the continuous improvement of environmental protection requirements, molding machines will continue to improve in energy conservation and emission reduction.

Use environmentally friendly materials and processes to reduce waste and pollution during processing and achieve green manufacturing.

Summary

Molding machines play an important role in modern manufacturing and are key equipment to ensure mold quality and production efficiency.

By choosing the right molding machines, enterprises can improve production efficiency, reduce production costs, and ensure product quality.

In the future, with the development trend of intelligence, high precision, and multi-function, molding machines will continue to play an important role in 

industrial manufacturing and provide strong support for the development of all walks of life.
