Injection Molding Knowledge Center

The raw materials commonly used for injection lenses are highly transparent PC and PMMA. Impact-resistant, wear-resistant, and inexpensive are their advantages. Its advantages are good transmittance, and the processing technology is simpler than that of PC, which can be processed by rotary vertical horizontal injection molding machine. For the injection molding of spectacle lenses, the quality […]

In the injection molding process of vertical injection molding machine, temperature is a very critical factor, and its level directly affects the quality of injection molding products So, what are the disadvantages of too high injection molding processing temperature? Thermal deformation of machinery: The moving parts with different thermal expansion coefficients of hydraulic components are

Injection molding machine is a very common type of plastic machinery. For friends who use and buy injection molding machines, it is first necessary to understand the performance of a good injection molding machine, and what aspects need to be evaluated in order to choose a suitable injection molding machine. Let’s find out how much

Plastic light guide plates are used in almost all liquid crystal displays. The materials used in the light guide plate are basically PMMA or PC plastic with good transparency. Injection molding machines are available in sizes from 55T to 300T: Medium and low-end products use hydraulic driven mechanical injection molding machines. Medium and high-end products

Plastic glasses: glasses include myopia glasses, reading glasses, sunglasses, etc. They are injection molding methods using vertical horizontal injection molding machines, which mold a certain number of spectacle lenses at one time, with simple coloring and low cost. Generally, PMMA materials are used, and fiber, transparent nylon or PC plastics are used for higher requirements.

When discussing plastics, most people are familiar with the general concepts. However, the vertical Bakelite injection molding machine may be less known, even among professionals in the plastics industry. Understanding Bakelite powder is essential, as it differs from other plastic materials. There are two primary methods to distinguish Bakelite from other plastics: 1. Knife Pin

The key handle lagging can be injection molded with a disc vertical injection molding machine There are many applications of disc vertical injection molding machines, such as auto parts and electronic 3C accessories, which we often see and use in daily life. For example, the keys we use every day (electric car keys or car

With the flourishing global economy, the demand for turntable vertical injection molding machines is also increasing. Consequently, the competitiveness among manufacturers of these machines is continually enhancing, and the development prospects for turntable vertical injection molding machines are very promising. So, what are the basic steps for loading, unloading, and handling the molds of a

Pressure instability is a common issue encountered during the operation of vertical injection molding machines. For instance, an injection mold may initially fill completely, but after producing several molds, dissatisfaction may arise. Occasionally, the machine may produce empty molds. If operations continue under these conditions, problems may arise, or one might notice that the quality
