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

1. Inspection and maintenance of the school table mould school table mold when loading the mould 2. School table mould maintenance in the production table Observe frequently and feel the status of the school table mold during production. If any abnormalities are found, stop the machine immediately for inspection and eliminate them in time. Start production

The plastic fruit crate, is usually much more expensive than the carton and wooden crates. But the plastic crate is more popular on the market because it can be used repeatedly for many times and the plastic material is recyclable.If you are planning to start plastic fruit crates molding business, check the plastic fruit crate

With the development of the economy, more and more enterprises have paid more attention to the practical value of CAE in design and production from the past purely focusing on the common software for finite element CAD. The full name of CAE is Computer Aided Engineering, that is, computer-aided engineering, but at present, it is

1. Why do you need to open the exhaust groove During the injection molding process, when the molten plastic enters the mold cavity, the air in the cavity needs to be exhausted instantly, including the air existing in the cavity and the gating system, and the water produced by the evaporation of moisture contained in the

Playground slides are common entertainment facilities in kindergartens. There are various structures of slides, including ups and downs, slides down slopes, and spiral rotations. Playground slides are commonly designed and manufactured with materials such as PE and PP. Safety needs to be paid attention to when designing the product. The material itself is
