As the core equipment in the material processing field, molding machines transform materials such as plastics, powders, and fibers into high - precision industrial components by precisely controlling temperature, pressure, and time parameters. This article will systematically analyze the working principles, technical characteristics, and industry applications of six mainstream types of molding machines.

 

I. Carbon Fiber Hot - Press Molding Machine

This equipment achieves the compounding of carbon fiber cloth and resin matrix through high temperature and high pressure, forming composite material products with both light weight and high strength. Its core advantages are as follows:

1. It adopts multi - stage pressure and temperature control technology, with a maximum pressure of up to 500 tons and a pressure accuracy error ≤ 0.5mm.

2. The oil heating system achieves a temperature uniformity of ±3°C, and the heating rate can be adjusted in sections through PLC programming.

3. The servo hydraulic system saves 50% - 70% more energy than traditional equipment, and is especially suitable for fields with strict requirements on material properties, such as aerospace and drone propellers.

 

II. Glass Fiber Hot - Press Molding Machine

According to the characteristics of glass fiber composite materials, this type of equipment is equipped with pre - heating, pressure - holding, and pressure - compensating functions:

1. The multi - stage pressure increasing technology ensures that the materials are free of bubble defects.

2. It supports the vacuuming process to improve the inter - layer bonding strength.

3. It is mainly used in the manufacturing of automotive lightweight components and wind turbine blades.

 

III. Servo Powder Molding Machine

An efficient equipment specially designed for the powder metallurgy and electronic ceramics industries:

1. It automatically completes the processes of powder filling, pressing, and demolding, with a single - machine production capacity of up to 600 pieces per hour.

2. The closed - loop servo system achieves a pressure accuracy of ±0.5%, and the product density consistency reaches 98%.

3. It is suitable for the production of precision components such as cemented carbide tools and magnetic materials.

 

IV. Automatic Box - Opening and Forming System

A packaging equipment integrating manipulator and visual inspection technologies:

1. It has a processing speed of up to 20 boxes per minute and is compatible with different carton sizes.

2. It is equipped with a grating safety protection system, meeting the hygiene standards of the food and pharmaceutical industries.

3. It has a high degree of automation, reducing manual intervention by 80%.

 

V. Multi - Functional Stuffing Molding Machine

A multi - task equipment in the food processing field:

1. It integrates the functions of dough sheet pressing, strip rolling, and stuffing injection, supporting more than 30 types of pastry shapes.

2. It has a weight adjustment accuracy of ±1 gram and a daily output of up to 50,000 pieces.

3. It is suitable for the large - scale production of stuffed products such as mooncakes and flaky pastries.

 

VI. Thermoplastic Molding Machine

Through the sheet heating and mold forming processes, it can achieve:

1. The molding of complex curved surfaces with an accuracy of 0.1mm.

2. The in - mold labeling (IML) integrated technology.

3. It is widely used in the packaging fields such as household appliance panels and medical trays.

 

The technological iteration of molding machines has always revolved around material characteristics. Taking carbon fiber equipment as an example, the three - beam and four - column structure combined with the T - slot mold fixing system ensures that the flatness during the molding process is ≤ 0.5mm. In the future, with the popularization of the linkage between intelligent temperature control systems and manipulators, the molding efficiency and yield will continue to improve, promoting technological innovation in the high - end manufacturing field.
