Injection Mold
Injection Molding vs. Rapid Tooling: How to Choose?
These processes are central to medium and mass-volume plastic part manufacturing. The decision often comes down to a trade-off between upfront investment, lead time, and long-term part cost.
| Feature | Rapid Tooling | Injection Molding |
|---|---|---|
| Mold Cost | Lower | Higher |
| Lead Time | Shorter | Longer |
| Ideal For | Prototyping, Bridge Production | Mass Production |
The VOK team integrates this analysis into the initial project evaluation. We examine your requirements for volume, timeline, and budget to recommend the optimal manufacturing strategy.
Our 6-Step Injection Molding Process:
- ESI & Quote: We start with expert advice and a transparent quote.
- Order & Plan: The project kicks off with order confirmation and mold planning.
- Mold Build: We design, procure, and manufacture the precision mold.
- Trial Run: First samples are produced for evaluation.
- Sample Approval (Key Milestone): You test and approve the samples.
- Mass Production: We ramp up to full-scale production upon your approval.
Case
Process: Two-Shot Injection Molding
Materials Used: Black ABS (structural) + Clear PC (optical)
Solution: A sophisticated molding technique that overcomes the limitations of single-material designs and secondary assembly. It enables the seamless integration of two distinct polymers—such as the toughness of ABS and the clarity of PC—into a single, high-value component within one production cycle.
Applications:
Automotive: Dashboard indicators, combining a durable ABS base with a clear PC lens.
Consumer Electronics: Device housings, featuring a colored ABS body and a transparent PC window.
This process molds flame-retardant ABS plastic around brass inserts, creating integrated components with combined benefits:
- Brass inserts provide strong threads & excellent conductivity
- FR ABS plastic ensures flame resistance & electrical insulation
- One-step molding eliminates assembly and enhances durability
Typical Applications:
- Electrical connectors & enclosures
- Industrial controls & safety housings
- Devices requiring secure fastening and fire protection This method is ideal for functional parts needing metal’s strength with plastic’s safety and design flexibility.
