Note：1)If gate type is banana or submarine gate，then the distance will be added about 10mm 2)Number of precision CNC processing mold base is an integer (then mold core should be 0.5 higher) https://youtu.be/rVBRZzbCDlc All copyright reserved by plastic mold factory Sositar Mould
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
What should we pay attention to the ejecting system? 2.1 Keep at least a distance of 3/32” between ejector hole edge and other holes; 2.2 A clearance of 1/64’’ should be kept for ejector holes on the ejector plate; 2.3 A clearance of 1/32’’ should be kept for ejector holes on the plate of injection
1)Ejector position:Ejected 10 – 15mm away from the edge of molding product (controlled by the retainer plate) 2)Ejection Types 1.Pin Ejector 2.Blade Ejector 3. Ejector Sleeve 4. 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
