Stripper Bar Ejector 5. Stripper Plate Ejector 6. Lifter 7. Air Ejector 3)Basic Ejection Requirements Product evenly ejected without ejection marks, unbroken and in shape; Main ejection parts: […]
【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 […]
Mold Trial Steps and Instructions Mold Trial Steps (1) Before mold trial, dry the raw materials first. All materials need to be dried except PE/PP. It is a standard practice to perform the trial with new materials. (2) Mount the mold onto the center hole and keep it aligned. It is enough to set the clamping […]
With the rapid development of the plastic industry, as well as the continuous improvement of general-purpose plastics and engineering plastics in aspects like intensity, plastic molding products are gaining a wider and wider application scope, leading to an increased application quantity of plastic molding products. Composed of several groups of parts that include the molding […]
Tips for Mold Disassembly: Able to read mold assembly drawings, and understand how each part and component functions and works, as well as how they are installed and mated. Check parts, standard parts and special assembly tools against the checklist shown on the drawings; Select appropriate general-purpose assembly tools (such as screw drivers, Allen wrenches, copper […]
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 […]

Designing Your Plastic Part When designing parts for injection molding, the manufacturing process is an important consideration. Injection molding is a process in which solid thermoplastic resin pellets are melted, injected into a mold, and then cooled back to a solid state in a new form. During Boss both the injection and cooling stages of […]
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 […]
