Part craftsmen typically provide mold design job books based on molded part task books. To assure the logic and consistency of the mold manufacturing process, optimize the processing process, and improve mold manufacturing progress, each mold factory normally develops a process standard fit for its factory, including using unique injection mold parts.   This article will discuss common injection mold parts, their applications, and things to consider when employing them throughout a factory’s machining process.   Types Of Injection Mold Parts: Core & cavity insert: In injection molding, the mold core refers to a solid component that is used to create the internal features and cavities of a molded part. It is typically made of hardened steel and is separate from the mold cavity itself. Mold cores are used in conjunction with the mold cavity to form the complete shape of the molded part.   Lifter: The injection mold lifter is an essential component that makes the ...

1, filling defect It always show uncomplete filling or edge collapse,it will dective product,waste material,labor and time.ther are many possible reason, such as nozzle temperature is too low,not enough supply,flowablity not good,injection pressure is low,the gate is too small or not right position,the mold surface is not smooth enough,nozzle is blocked,venting problem     2,flash or burr It always happen in parting line,it will increase the difficulty of machining or dishape,even defective.the possible reason such as:nozzle temperature too high,injection too much material,flowbility is very good,injection pressure too high,clamping force too small     3,sink mark It always caused by material shrink after injection molding,possible reason such as:nozzle temperature too high,resin supply not enough,shrinkage is too big,injection molding pressure too low,holding time too short,injection speed too slow,mold teperature too high,cooling time too short,the thickness of pr...

DESIGN GUIDES Best Practice Best practice design guides aim to help create complex shapes while:   • Allowing plastic to flow easily and uniformly around the part. • Allowing plastic to flow easily and uniformly around the part. • Allowing the plastic to cool quickly and evenly, resulting in a stable and accurate part.   These general tips will improve part quality, mould ability and cycle time based on known implementation and characteristics of the injection moulding process.   Note: Design guides are broken often and still result in successful moulded parts.   To do achieve this careful consideration and understanding of many parameters is needed including;   • The part’s mechanical requirements, • Mould flow, • Temperature control within the tool, • Polymer selection • Filler requirements • Adjustment of part geometry.                   ..       &n...
