Molds Making
Shanghai Elue Molds Making Service
Plastic Mold is an important part of the equipment manufacturing industry. The mass production of plastic injection molded parts have the advantages of high efficiency, high consistency, low energy consumables, high precision and complexity, etc. Therefore, they are widely used in mechanical, electronic, automotive, information, aviation, aerospace, military, transportation, building materials, medical, biological, and other industries. Actually,about 60%~80% of the parts in the above industries rely on mold processing.
Molds Design
Wall thickness:Uneven wall thickness can cause surface shrinkage, air holes or fusion marks.Material shrinkage: Due to the shrinkage rate unevenness during injection molding, the accuracy of injection molded parts is obviously lower than that of metal parts, and the dimensional tolerances of mechanical parts cannot be simply applied.Drafting angle: Proper drafting angles can avoid product straining or top injury.Injection parts deformation: Improve the rigidity of injection molding products structure, try to avoid flat structure, set reasonable set flange, concave and convex structure,and reasonable application of reinforcement ribs.The mold opening direction and parting lines should ensure that the core pulling slide mechanism is minimized and the effect of the parting line on the appearance is eliminated.Molds Making Processes

Molds Making Processes
After customer confirmed mold designs,the first thing is to prepare mold steel, then we start on CNC milling. A injection mold comprises two main sections. One section is the mold base which can be purchased from the professional mold base factory. While the other section is the mold core or cavity which are customized machined based on mold designs.On most cases, there are electrodes needed to EDM the complex shapes or high precision small workpieces.ase a PO if the quote meets your request along with down payment.
Molds EDM Machining
EDM means electrical discharge machining, generally we use copper as an intermediate. EDM machining has been widely used in molds making industry, with its advantages of small machining allowance, high processing accuracy, short production cycle, low manufacturing costs and other outstanding advantages.
Molds Polishing
Plastic injection mold polishing not only increases the beauty of the workpiece, but improves the corrosion resistance and wear resistance of the steel surface, also it can facilitate the subsequent injection molding process, such as making plastic products easy to demold, reducing the injection molding cycle, etc.There are 6 types of mold polishing techniques which includes Mechanical Mold Polishing,Chemical Mold Polishing, Electrolytic Mold Polishing, Ultrasonic Mold Polishing, Fluid Mold Polishing and Magnetic Mold Polishing.
