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…
Troubleshooting in the injection molding field serves as a pursuit that comes about to figure out the explanation for and remedy for, faults present in a molded component. This process generally happens whilst components are made and come about, once…
SAFEGUARDING THE MOLD A mold is an extremely expensive tool. The engineers may have to spend several hundred (sometimes thousands) of hours developing and creating their products before these are ready for manufacturing. In addition to the fix expense, destroyed…
Regardless of whether the plastic mold you are using or storing needs to be repaired, there is a great deal of deterioration that will occur through its use or storage. It becomes more damaging as it is used harder or…
Plastic material identification Judging thermoplastics and thermosets: All thermosets have no softening process when heated or burned, only become brittle and coked; All thermoplastics, which are heated or burned, undergo a soft melting process, but different plastics burn. The phenomenon…
