Tooling Making

Tooling Design

  1. Computer Simulation:
    In accordance with the position of the gate and assembly program by client’s 2D and 3D design and use mold flow simulation SOLIDCAST software to simulate the speed of melting pouring and the gate in equal proportions into the case analysis of whether defects or shrinkages occur. The program can be determined if there is no occurrence of defects or shrinkages.
  2. Computer Simulation
    The result chart of mold flow analysis. Red spot means shrinkage inside.
  3. Calculation Shrinkage:
    During melting pouring process, under the wax and liquid iron will pass under the iron and other processes at the state of contraction different body type has not seen the same situation.
  4. Drawing of Pattern:
    Depending on different types of casting, appropriate design of draw of pattern for operations that can speed up work efficiency and maintain the quality.
  5. Drawing of Pattern
    The illustration of drawing of pattern.
  6. Soluble Wax Design:
    Making soluble wax mold is a likely situation if the internal shape is complex and it is difficult situation to draw of pattern while lost wax casting. The advantage for soluble wax mold is internal dimensionally stable and good roughness.
  7. Soluble Wax Design
    Soluble wax and main body wax. Soluble Wax Design
    The look of Soluble wax after melting.
  8. CNC Machining:
    The data is going to be sent to CNC processing plant to machine mold after finishing taking apart the mold design.
  9. CNC Machining
    Tooling is made by CNC progress.
  10. EDM:
    When CNC machining cutting tool face radius is too small or deep hole to machine. The choice is to use electrical discharge machining method.
  11. EDM
    The use of copper electrode discharge.
  12. Assembly:
    When the mold returns from CNC processing plant, it needs to be done location and permeability assembly work.
  13. Assembly
    Assembly Process.

Mold Inspection Approach

  1. Cleaning wax mold and testing to check for burrs and dimensional inspection.
Mold Inspection Approach
Check the dimension of wax.

Wax Injection

  1. Wax is injected into the mold. The time, pressure and temperature are controlled under SOP process in order to ensure the stability of the standard size.

Fix Wax

  1. When the mold using longer will produce too much burrs and shell mold line, it need to rely on repair personnel to remove and repair and fix wax pieces flatness.

Assemble the Wax

  1. According to the proposal for assembling, wax and die head will be fabricated and send onto the conveyor belt to the next process.
