1. PC Material (Polycarbonate) 1. PC Material (Polycarbonate) Features ①Amorphous plastic, no obvious melting point, glass transition temperature 140℃~150℃, melting temperature 215℃~225℃, molding temperature 250℃~320℃. ② It has high viscosity and is sensitive to temperature. It has good thermal stability within the normal processing temperature range. It basically does not decompose when staying at 300℃ for

Polyoxymethylene is divided into two types: homopolymerization and copolymerization. Copolymer has good short-term strength while homopolymer has good flexibility. The copolymer has a softening point 10°C higher than that of homopolymer, has a high thermal deformation temperature under load, good thermal stability, and a wide molding temperature range. Commonly used in industry is acetal copolymer.

The future development direction of injection molds: 1: High precisionWhether the dimensional accuracy can be achieved is the most important factor in manufacturing high-precision, high-quality, high-tech products. Japan and Germany were the best in the past. With decades of continuous learning and innovation, a large number of companies specializing in high-precision mold manufacturing have emerged

The close relationship between injection speed and product quality makes it a key parameter for injection molding. By determining the beginning, middle, and end of the filling speed segments, and achieving a smooth transition from one set point to another, a stable melt surface velocity can be ensured to create the desired molecular extraction and

We have defects in the gate area during the process of injection mould. What is the reason for this phenomenon? Is there any good way to solve it? Causes Of Light Line In Injection Mould In the point gate design perpendicular to the direction of the part, a radiation system consisting of different color depths and glosses centered on the gate appears on the surface of the part during injection molding, called a ray of light.  There are generally three manifestations, namely dark lines with dark background, dark lines with dark background and dense and white dark lines around the gate. Such defects mostly occur when injecting polystyrene and modified polystyrene mixtures, and are related to the following factors: the two materials have differences in rheology, colorability, etc., and the flow rates of the stratosphere and turbulent layer of the pouring system.  There are differences in heating conditions; plastics produce burnt wires due to thermal decomposition; gaseous substances interfere with the plastics when entering the mold. https://www.sciencedirect.com/science/article/abs/pii/S0263436823002123 Injection Mould Light Line Solution Causes Of Cold Spots In Injection Mould Cold spots mainly refer to the foggy or brightcolored spots near the gate of the part or the curved scars starting from the gate that look like earthworms sticking to it.  They are caused by the plastic front entering the cavity or due to excessive pressure holding. It is caused by the cold material that is later squeezed into the mold cavity. The front material transfers heat due to the cooling effect of the nozzle or runner, and is partially cooled and solidified before entering the mold cavity. When it expands through the narrow gate and is injected into the mold cavity, the melt ruptures, and is then heated by the subsequent heat. The molten material pushes around and becomes a cold material spot.

There are many standards to measure the transparency of some injection molded products, including transmittance, haze, refractive index, birefringence and dispersion. See whether the hardness and strength of the material are required. Transparent injection molding products generally use PS, SNA (AS) materials, PMMA and other materials, but they all have a brittle problem that needs
