Plastic injection molding outsourcing
From the perspective of efficiency, quality and cost, in-house manufacturing of injection molded parts as part of the customer’s final product is a major challenge. […]
Introduction To Plastication
The raw materials of plastics fall into the charging barrel from the hopper and are sent forward by the rotating screw. While in the charging barrel, the plastics, on the one hand, receive heating and warming from outside of the barrel, and on the other hand, are compacted due to the gradual reduction of the [...]
How to solve ejector mark issue in injection molding
During ejection, white ejector mark usually appears on the plastic parts in contact with the ejector pin and such ejector mark will easily crack during actual use of the products. The causes thereof comprise: […]
how to solve injection parts stick to the mold
The injection parts stick to the mold, making it rather difficult for ejection. The causes thereof comprise: […]
What Is Dark Spots Or Black Lines Of Plastic Parts ? And How To Solve
Color is normal on the surface of products, though black spots or lines occasionally occur. The dark spots or black lines are fundamentally caused by the thermal degradation of material or carbonization of impurities due to various factors. The raw material is mixed with impurities (such as impurities falling off when the operator is unripping [...]
What Is Aberration Of Plastic Parts? And How To Solve
Aberration refers to the discrepancy of color on the products wherein the tint is uneven. The causes whereof comprise: […]
Injection molding need a perfect Heat Exchange system
In the molding industry, Mould is one of the essential production tools, but how to evaluate a set of mould, The heat exchange efficiency is an important parameter, In part two of our three-part sub-series on mold water cooling systems, we review water quality and its impact on mold performance. […]
Copper Alloy benefit plastic injection molding
Copper is the most thermally conductive of the common solids; only silver, cubic boron nitride and diamond are more conductive. This makes copper an excellent choice for plastic injection molds that must remove heat from the injected, molten plastic to make it solidify. However, copper is neither hard nor strong enough in its pure form [...]
More details about plastic Injection Molding
Plastic injection molding produces plastic parts by forcing molten plastic into a mold where it cools and hardens. In plastic injection molding granular plastic is fed by gravity from a hopper into a heated barrel. […]
Plastic Injection Molding Design Considerations
Use rounded corners. Add draft to walls to allow easy ejection. […]
