Tooling & Molding

Tooling & Molding

Plastic injection molding and mold tooling for housings, covers, and structural plastic parts. Bridge from prototype validation to small-batch production.

Why Product Teams Choose Us for Molding

Switching mold suppliers mid-development kills timelines. We bridge prototype and production with consistent engineering communication, mold ownership clarity, and parts that match your approved T1 samples.

1

Plastic-Specific DFM

Wall thickness, draft angles, gate placement, and undercut analysis before cutting steel — so your first shots aren't your last design iteration.

2

Prototype to Production Path

Start with aluminum tooling for fast validation, then transfer to hardened steel molds using proven gate and cooling strategies from T1.

3

Integrated Finishing

Texture (MT spec), pad printing, ultrasonic welding, and insert molding coordinated with your molding schedule — one vendor, one timeline.

End-to-End Molding Capabilities

From single-cavity prototype tools to multi-cavity production molds — we scale with your product launch.

Injection Mold Design

3D mold flow analysis, gate and runner design, cooling layout, and ejector planning. Designs optimized for your resin, cycle time, and cosmetic requirements.

Aluminum / Steel Tooling

7075 aluminum for rapid tooling (1K–10K shots). P20, NAK80, and hardened steel for high-volume production with hot runner or cold runner systems.

Prototype Molds

Fast-turn aluminum molds for design validation, fit checks, and market testing — typically 2–4 weeks from approved DFM to first shots.

Production Molding

50–200 ton injection presses for ABS, PC, nylon, PP, and engineering resins. In-process SPC, cavity pressure monitoring, and dimensional QC on every run.

Materials & Resin Selection

Resin choice affects strength, appearance, UL rating, and mold design. Tell us your application constraints — we'll recommend a grade or mold to your specified material.

Engineering Resins

  • ? PC / PC-ABS (impact, transparency)
  • ? Nylon (PA6, PA66, glass-filled)
  • ? POM (Delrin) — low friction

Commodity & Specialty

  • ? ABS, PP, HDPE
  • ? TPE / TPU (overmold grips)
  • ? Flame-retardant grades (UL94 V-0)

Post-mold operations — painting, plating, laser marking — available in-house. View full material library →

Industries We Mold For

Plastic components where cosmetic finish, assembly fit, and production repeatability define product quality.

Consumer Electronics Housings

Enclosures, bezels, battery covers, and internal structural parts with tight snap-fit and texture-matched surfaces.

Medical Device Covers

Biocompatible-grade resins, clean-room compatible molding, and documented process validation for regulated applications.

Automotive Interior Parts

Dashboard trim, console components, clip features, and soft-touch overmolded grips with automotive-grade textures.

★★★★★
"NDA signed same day, communication in clear English, and the aluminum prototype molds for our sensor housings were exactly to spec — T1 parts fit our PCB assembly on the first try. Will order production steel tooling next."

Common Questions

Who owns the mold tooling? +

You own the mold upon full payment. We store and maintain it at our facility for production runs, or ship it to your designated location on request.

Aluminum vs. steel — which should I start with? +

Aluminum is ideal for prototypes and low volumes (under ~10K shots). Move to steel when you need higher volume, tighter tolerances over time, or abrasive/glass-filled resins.

What is included in T1 sample approval? +

Typically 10–50 sample parts, dimensional report, and photos. You approve fit, cosmetics, and function before we release the mold for production quantities.

Can you mold with inserts or overmolding? +

Yes. We support brass/threaded inserts, metal bushings, and TPE overmold onto rigid substrates. Specify insert type and placement on your drawing.
