Difference Between two plate mold and three plate mold
Three plate mold VS Two plate Mold Appearance difference Between two plate mold and three plate Mold With regard to appearance, the biggest difference between the two plate mold and the three plate mold is that there is a stripper plate between the upper clamping plate and the cavity plate of the three-plate mold. Structures difference Between…

Lifter Design for Plastic Injection Mold
【LIFTER】 In essence: a combination of the ejection mechanism and the side-core pulling mechanism. Stroke：S=undercut+（1～3）mm Thickness：8～12mm Angle：not more than 15° Ejectors are allowed to place near the lifters.but not too many. 1、【lifter without base】 Thickness (D)＝S (undercut)＋（2/3Ø）mm Width (W)≥12 （If the width less than 12mm,use lifter with base） 2、【Lifter with base】 Stop block：Steel…

PC/ABS plastic injection molding resin
What is the PC/ABS? PC/ABS is a blend of PC (polycarbonate) and ABS (acrylonitrile-butadiene-styrene copolymer), and a thermoplastic made of the polycarbonate and ABS alloy, offering the most desirable properties of the two materials – the processability of ABS and the mechanical properties, as well as resistance to impact, temperature and UV of PC. It…

PEEK(polyetheretherketone) plastic injection molding material
1. Basic Concepts of PEEK PEEK, AKA Poly-ether-ether-ketone, is a special engineering plastic that possesses high thermal stability and a high mechanical performance. The main chain is a high molecular polymer formed by alternation of an ether bond and a ketone bond, of which the typical polymer is polyaryletherketone. The unit structure is as shown…

Mold Adhesion (sticking) in Injection Molding Process
Mold adhesion, also known as sticking sprues or parts, is caused by improper contact of the nozzle tip with the sprue bushing, which does not allow sprue or part release and good filling. Usually, the diameter of the main runner needs to be big enough, so that the sprues are not completely solidified when injection…
