Mold Manufacturing and Assembling

Computer Numeral Control Machining Computer Aided Manufacturing.
      After received the checked program files and printed copy from CNC Programming Section, get the assigned Steel; Copper and Mold Base from the Warehouse; Milling Section or Grounding Section then start the proper processing.
      Mount the Steel; Copper or Mold Base onto the CNC Machining Centre or CNC Machine, calibrate the related co-ordinates and set the Datum.
     Loading the related program to the machine and double check all the information, such as Mold Number; Steel Insert Number or Copper Electrode Number.
     This is for sure that all the Parts and Accessories in house are having their own marking numbers and all of them are traceable.
     After completed the machining, Parts and Accessories will send to QC Department to inspect the critical dimensions before released to EDM and / or Wire Cutting Sections for further processing.

Electrode Discharge Machining

     When QC inspectors completed the dimension check, electrodes will send to Polishing Section to polish away the surfaces to their requirements then release to EDM Section.
     EDM Technician will check the number of the Work Piece (Steel Insert; Beryllium Copper or others); the Copper Electrodes ; Set up Data Sheet and the EDM program number, to ensure all these items belong to the same job order.
     Mount the about work piece onto the EDM Machine and calibrate and reset the Datum, input the EDM program and Settings as according to the requirement. Double check the above then start the testing procedure, confirmed the tested EDM position and the settings are correct then start EDM process.
    During the EDM processing, frequently check the flowing of the fluid to ensure no deposition of carbon on the work piece or no undercut was made. Check the dimensions of the work piece with measuring instrument or gauge during EDM process if necessary.

EDM Wire Cutting Section
EDM Wire Cutting Section will handle all the Wire Cutting Works such as Pockets; Inserts; Lifters; Slides; Slots and Holes. For all these processes must according to the drawings and requirements release by the Engineering Department and under the monitoring of our strict Quality Control System.

Fitting and Assembling
Fitting and Assembling
Fitting and Assembling Section responsible for the final completion of the mold, all the Cavity & Core Inserts; Slides & Lifters; Parts & Accessories; Screws & Pins and other components must be fitted and assembled by the technicians of this section. They reflect the ability; capability; quality of the mold manufacturing and represent the reputation of the company.
