Mold Design

TWNCCAD, Alphacam
  1. After the Customer provides 3D Data of the product, KST designs the mold according to required material characteristics and production requirements.
  2. A injection mold is usually composed of two halves, the fixed cavity side, and the moving core side. The core side slides open and close.
  3. While designing the mold, we will use Alphacam CAD/CAM software to simulate the process and validate mold design.

Mold Scheduling & Dispatch

ERP / Automated Storage Retrieval System (ASRS)
  1. Production Management receives and registers the design drawing.
  2. ERP system provides estimate, projects delivery schedule and assigns barcode identification.
  3. Provides Input-output processing operation control.

CNC Machine Center (MC)

Kafo VMC-850

Injection Mold

  1. Order 3rd Party Steel Blocks for cavity and core main inserts
  2. Use a milling machine to mark the position of screw holes and cooling lines
    Drill through holes for cooling lines
  3. Block the end of through-holes with aluminum plugs to form cooling loops
  4. Cut off residual aluminum

CNC In-hole Grinding

GE Fanuc Series 16i-M, Hauser S45 Jig Grinder

CNC machining of the core and cavity insert can take several hours each.

CNC Wire Cutting EDM

TWNCAD, Agie Cut200, Seibu M500S

We use wire EDM machines to cut through holes for ejectors. The precise ejector can go through holes to ensure accurate sizing thus avoiding flash issues during the injection molding process.

CNC Optical Grinding & Forming

Waida PGX-2500SP

This SPG-X standard profile optical grinder offers improved ease of operation and visibility. The projector is manufactured under rigorous quality control to deliver visibility and reassuring support. The new standard-equipped LED transmitted illumination provides clear projections. Meets various grinding needs due to a wide range of optional equipment available.

CNC 3D forming - Electrode Making

Vertical Milling & Boring Machining Center AV-70S
  1. Complex shapes in steel can not be achieved by CNC milling. Instead, this can be achieved using Electrical Discharge Machine (EDM). The electrodes are important to the EDM process.
  2. We use CNC machines to cut the copper blocks which can take several hours to achieve the specified shape.
  3. The quantity of electrodes required is determined by the complexity of the mold. For instance, hundreds of electrodes are required for some molds.
  4. Each piece is individually CNC machined, and subsequently deburred.

CNC Die-sinking EDM

Mitsibushi EA8PV Die-sinking EDM

Material is eroded from the material workpiece by means of a pulse discharge between electrodes and steel insert submerged in water.  The electrode and steel insert are close to each other but never touch.

Precision Coordinate Measuring Machine (CMM)

Zeiss Prismo

Our accuracy lab provides high-speed scanning and maximum precision and follows ISO quality standards entirely. Our coordinate measuring machines measure with uncertainty as low as 0.9+L/350 μm. Computer Aided Accuracy (CAA) corrects all dynamic influences on the machine to optimize precision even during high-speed scanning with tolerances of one micrometer or less.
