On plastic injection products, especially for raw materials such as ABS, PP and PC, you will often see shiny stress marks on the surface of products, such as injector pin stress marks, insert stress marks and stress marks of wall…
If want to reduce or eliminate cracking of injection-molded polycarbonate, it can take two measures: Reduce internal stress; Or improve the cracking resistance of plastics. What can do to reduce the internal stress of the PC injection molding process? Mold…
PC/ABS Injection Molding PC/ABS, the mixture of Polycarbonate and acrylonitrile butadiene, is a thermoplastic plastic made of polycarbonate and polyacrylonitrile (ABS), which combine the excellent characteristics of the two materials, the injection-ability of ABS and the mechanical properties, impact strength,…
What is the definition of Precision Machining? Precision machining, also known as CNC machining, removes material from a part while holding close tolerances. A computer numerical control or CNC generally controls a precision machine. Precision machining makes part contributing…
glass fiber-rich surface in injection molding During the mold testing, there were occasional appearance problems as radial white marks would appear on the surface of the product. It is noted that the appearance quality problems became more serious with the…
A system which constant transfers heat from the melt in the mold or heats the mold to the injection temperature is called a temperature control system. Mold temperature refers to the surface temperature of the mold cavity that comes in…
Strategic injection molding and tooling procurement is the process of establishing service supply channels at the lowest total cost, and is a systematic, data analysis-based procurement method. On the one hand, through understanding the injection molding and tooling supplier’s production…
How to control injection molding part size Mold and product requirements are continuously changing, which has created many difficulties in the production process of molds and products. The challenge lies in determining the best method of controlling the geometric dimensions…
Rusting plastic molds is a normal phenomenon and caused by special reasons. It is not always due to quality problems of steel products. Melt Decomposition Some plastic raw materials will release volatile gases after being heated, which are corrosive and…
Storing Molds During downtime, plastic molds are generally removed from the molding press and put into some maintenance. The mold warehouse usually has s few heavy-duty steel shelves where the molds are positioned onto and labeled for identity. Generally, the…
