Five Points of Knowledge of Injection Molds Introduction Injection molds are crucial tools in the manufacturing of plastic parts. They enable the mass production of intricate and high-quality plastic components. This article aims to provide comprehensive knowledge about injection molds from 5 points of mold types, standards, mold steel selection, hot runner systems, and surface requirements. Understanding these key elements is essential for designers, engineers, and manufacturers involved in the plastic injection molding industry.

Auto Handle Part material : PC+ABS Mold steel : Core and cavity with Groditz 1.2344 (HRC48-52)ESR : Mold base with P20. Cavity NO: 3+3 Mold size :800x900x620(mm) Hot runner : point gate with Synventive (6 drops) Surface polish : B1 800# Production cycle : 40s Mold built : 40-45 days Mold life : 500K

Mold Description: Mold Size : 600x600x510 Resin: PET +45%GF 1x2 Cavity Mold 2 Drop with Valve Gate Cycle Time:30s Clamping Force:180T Characteristic: The part is the electro-motor body case 1. It is include many dimension. Such as the concentricity and the concentric circles dimension. 2. The Melt flow rate of material is very high, It is easier appear the flash when the clearance is over 0.02mm. The mold temperate is about 120℃ to 140℃. So for the component clearance is very difficult to control. 3：Totally 450 dimension and all require to match the 2d drawing. the clearance is +/-0.05mm. 4. The material for this part, it is very easier to release and not need any draft.

Mold Description: Mold Size : 1040 X 885 X 470 Resin: BAYBLEND-T65 XF 1x1 Cavity Mold 1 Drop Hot Tip with sub gate Cycle Time:48s Clamping Force:250T Characteristic: 1.the outside surface of housing is form by 4 slide,it is easier appear the mismatch if not fitting well 2. The dimension of housing is also critical where need to fit the Horizontal Vanes. It need to fit perfect and easier to rotate. 3. Mold open Sequence guiding line: mold open. Slide of operation side and non-operation side will pull by Cylinder. and then bottom slid pull by cylinder.
