DFocus PROTOTYPE reviews prototype and bridge injection molding projects by material, tooling route, inspection scope, and production intent before confirming quantity and schedule.
- Quantity reviewed by tooling route
- Over 100 Thermoplastics Available
- Detailed DFM & Mold Flow Analysis
DFM and mold-flow review available when agreed during RFQ. T1 timing depends on tool complexity.
Advanced Molding Capabilities
Beyond standard injection molding, we offer specialized processes for complex multi-material parts.
Overmolding
Chemically bond multiple materials in a single part. Perfect for adding soft-touch rubber grips (TPE/TPU) to rigid plastic handles, improving ergonomics and durability without adhesives.
Insert Molding
Encapsulate metal inserts (threaded fasteners, bushings, contacts) within plastic parts. This enhances strength and reliability for electronic connectors, medical devices, and handheld tools.
Finishing & Secondary Operations
We deliver production-ready parts with a wide range of post-molding services.
Painting & Color Matching
Custom color matching (Pantone/RAL) and texture painting for aesthetic surfaces.
Pad Printing & Silk Screen
High-quality logo and text application on flat or curved surfaces.
Laser Engraving
Permanent marking for serial numbers, barcodes, and logos.
Ultrasonic Welding
Bonding two or more plastic components together securely without adhesives.
Heat Staking
Inserting metal components or joining parts using thermal deformation.
Assembly & Packaging
Full sub-assembly and retail-ready packaging services.
SPI Mold Class Standards
We adhere to SPI standards to help you balance mold life and cost. Choose the right tooling class for your production volume.
| Class | Cycles | Description | Steel |
|---|---|---|---|
| Class 101 | High-volume scope | Tool life and cycle assumptions confirmed by mold RFQ. | H13, S136 (Hardened) |
| Class 102 | Medium-volume scope | Production assumptions confirmed after tool design review. | P20, H13 (Pre-hardened) |
| Class 103 | < 500k | Standard production mold. Most popular. | P20 (Pre-hardened) |
| Class 104 | < 100k | Low volume production / Bridge tooling. | P20 or Aluminum equivalent |
| Class 105 | < 500 | Prototype mold. Lowest cost. | Aluminum / Mild Steel |
射出成形 FAQ
What plastics can you use with injection molding?
We support over 100 thermoplastic materials, including standard plastics (ABS, PP, PE) and engineering materials (Nylon, Delrin, PEEK, Ultem). We can also utilize custom compounds with glass, talc, or UV stabilizers.
Why should I use plastic injection molding?
Injection molding can become cost-effective when tooling cost, material, cycle time, and validation quantity are aligned. Unit cost depends on the approved tool route and production assumptions.
Do you handle mold storage and maintenance?
For production molds kept at our facility, storage and maintenance terms are agreed in writing during the tooling RFQ or purchase order.
What is the typical lead time for injection molding?
Mold fabrication timing depends on complexity, steel or aluminum route, texture, inserts, and trial scope. T1 and production timing are confirmed after tool review.
最低発注数量（MOQ）はありますか？
Minimum quantity depends on tooling route, material, setup, and validation stage. Aluminum and steel tooling options are reviewed against project economics during RFQ.
Do you offer overmolding and insert molding?
Yes, we specialize in multi-material molding including overmolding (soft-touch grips on rigid parts) and insert molding (metal inserts encapsulated in plastic).
