SAFEGUARDING THE MOLDA 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 molds result in…
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 kept…
Plastic material identificationJudging 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 is different.PP…
Gas-assisted injection molding is an innovative technology developed on traditional injection molding.GIM (Gas-assisted injection molding) was adopted in production in the 1980s.The gas-assisted injection molding system directly injects inert gas (usually nitrogen) into the melted plastic in the mold cavity…
2 plates mold,3 plates mold and hot runner moldWhen it comes to plastic injection molds, There are many classifications for plastic injection molds. The most common division is between cold runner and hot runner molds. In general, hot runners are…
A plastic mold hot runner system is a system used in the injection molding of plastics. The system injects molten plastic into the mold cavity through a heated runner system. This system is used to produce molded parts with intricate…
The Difference between insert molding and Double Color moldingThe so-called two-color injection molding refers to injecting two kinds of plastics with different colors into the same mold.It can make the plastic parts with two different colors and make the plastic…
Acrylic is also called polymethyl methacrylate (PMMA). Due to the defects , such as low surface hardness, easy scratching, low impact resistance and poor molding fluidity, the modification of PMMA appears alot. Such as copolymerization of methyl methacrylate with styrene…
