The first step in turning your idea into reality

We offer free DFM and plastic products demould consultation

What we can help about mold design?

  • . At Muyoung mould, we offer free advice to our customers on the possibilities of molded in plastic product development and how to save tooling costs while meeting the functionality of the plastic product.
  • . We provide a free DFM along with a quotation for the mould, so you will have a clear idea of the main details of the plastic product to be molded, and we will provide you with a mold flow analysis report for your reference if required.
  • . Before producing the mold, we will design a detailed 3D drawing and the mould we produce will be strictly designed in 3D to provide a guarantee for the mold to be changed after export.

Plastic Injection Mold Design Process

Muyoung mould provides 3D mold construction with file formats: STEP(.stp), IGES(.igs), PRT.prt,X_T(.xt) to customer for review and approval. If tool changes are necessary after the mould trial, we also update the 3D injection mold file and submit the correction method for approval.


CAE.Mold Flow Analysis

Mould design is the most important step in ensuring the quality of a mould. our project engineers, mold engineers and mould maker will take into account the product characteristics, customers’ specification, resin parameter and historical similar products to analyse the mold structure in order to achieve a more suitable mold design for the customer, and also reference to the mold flow analysis report to optimize cooling, filling, stress and deformation.


Preliminary Mold Design.DFM

  • Cavity number, resin and shrinkage, samples color and injection machine Nozzle R
  • Detail of the gate location and runner design
  • Part line of the mold, partial Core and cavity Plan;
  • All mechanical function of the injection mold, inserts, sliders and lifters; interchangeable inserts……
  • .Ejector pin sizes and locations, ejector plate or air valve;
  • Surface requirement, polish or texture;
  • Show all sprue bushing, leader pins, and return pin sizes and locations and mold size;
  • A layout of all cooling circuits and cooling size;
  • Show outline of attachment protruding beyond the outside of the mould on the Core and Cavity Plan, such as cylinders, supporting inlets, etc.
  • Suggestions for optimization: Optimization of the product to simplify the injection mold structure, reduce costs and increase mold life.


Final Tool Drawing.3D Mold construction

When the preliminary plastic mold design (DFM) has received feedback, the design must be detailed with all objects and features. Objective is to have the CAD file exactly as the real mold will be. This detailed file will receive approval or feedback from customer before start building.

Final mold design includes necessary assembly and detail information for future mold repair and maintenance. All part design revisions during or after mold build will require the mold drawings to be updated reflecting the new part configuration.

H13 steel is the most widely used and most representative hot work die steel grade, its main characteristics are

(1) High hardenability and high toughness.

(2) Excellent resistance to thermal cracking and can be water cooled in the workplace.

(3) Medium wear resistance, carburizing or nitriding can also be used to improve its surface hardness, but to slightly reduce the resistance to thermal cracking.

(4) Poor secondary hardening ability in tempering due to its low carbon content.

(5) Softening resistance at higher temperatures, but a rapid drop in hardness at operating temperatures above 540°C (1000°F) (i.e. a working temperature of 540°C can be tolerated).

(6) Small deformation from heat treatment.

(7) Moderate and high machinability.

(8) Medium resistance to decarburization.
