Injection Molding Knowledge Center

Vertical two-color injection molding machines are essential for the overmolding of soft rubber onto hard plastic components. This process often employs secondary molding techniques and specialized two-color molds. Secondary molds, specifically designed for applying soft rubber to rigid plastic, typically utilize materials such as artificial rubber, TPU, TPR, and TPE for the soft part, while […]

Injection molded products vary in characteristics and colors based on their specific applications. In this guide, MINHUI provides insights into color control during the operation of vertical injection molding machines, aiming to assist you in achieving better results. Choosing the Right Machine To ensure consistent color output, it is vital to select an injection molding

The injection method of the liquid silicone injection molding machine is hydraulic. The key to a silicone injection molding machine is to better handle various types of liquid silicone raw materials and ensure the pressure during the injection process. Usually, separate material barrels are used for mixing mechanical equipment to properly handle materials with different

Liquid silicone injection molding is a manufacturing process that involves injecting a heated silicone gel into a mold cavity to form a desired shape. This method capitalizes on the fluidity of the silicone gel, allowing it to fill the mold uniformly. The fundamental principle of this process includes heating solid silicone to its melting point,

There are numerous types of plastics, and thousands of plastic materials have been produced in the market. The use of plastics on vertical injection molding machines is also growing. The industry has classified plastics that can be used on vertical injection molding machines into the following categories: Thermoplastics: These plastics can be heated to a

PC, also known as polycarbonate, has very high mechanical properties, earning it the nickname “bulletproof glue.” PC has characteristics such as high mechanical strength, wide application temperature range, good electrical insulation performance, good dimensional stability, and transparency. It is widely used in electrical products, electrical instrument housings, and electronic components. Due to the high processing

Data statistics show that when purchasing a vertical injection molding machine, many people choose a vertical rotary injection molding machine. Why is that? After extensive communication and analysis, it has been found that the appealing advantage of a vertical rotary injection molding machine lies in its simplicity and convenience for automation. The wide operating range

An 85-120T vertical injection molding machine generally refers to a vertical injection molding machine with an injection weight of 105-250 grams. Models such as 80-120T fixed machines, sliding plate machines, and rotary machines can meet this requirement, and custom models are also available. However, the prices of vertical injection molding machines can vary greatly depending

When a vertical injection molding machine is operating, it may generate noise, which usually indicates that some parts of the machine are damaged or improper adjustments have been made by the operator. If there is noise, the cause should be identified promptly and repairs should be carried out in a timely manner. Insufficient hydraulic oil:
