Precision firearms injection molding

Plastimold supports firearms OEMs and tactical product teams with design for manufacturability (DFM), tooling, injection molding, and production support. Start by sending your 3D or 2D file through our firearm molding quote form. We will then connect you with our custom plastic injection molding and CNC machining teams and work with you to develop a quality production plan.

Plastic gun parts and accessories we mold

Plastimold molds custom plastic gun parts and accessories for firearms OEMs and tactical product companies. Typical programs include:
Injection molded gun stocks, magazine and rail parts
  • Ammo boxes
  • Butt stocks
  • Braces
  • Grips
  • Hand guards
  • Holsters
  • LED marker lights
  • Magazines
  • Optics
  • Rail systems
  • Hard cases

Grips and Butt Stocks

Grips and butt stocks designed for fit, feel, durable interfaces, and repeatable production for firearms OEM programs.

Braces and Hand Guards

Braces and hand guards engineered for durable geometry, stable interfaces, and consistent wall sections through production.

Holsters and Magazines

Holsters and magazines with consistent fit, finish, and interfaces for licensed OEM and tactical product programs.

Rail Systems and Hard Cases

Rail systems and hard cases built around consistent interfaces, durable geometry, and inspection requirements for tactical product programs.

Molded + machined assemblies

Molded polymer components paired with CNC-machined metal parts such as barrels and receivers, for licensed firearms OEM programs.

Materials for firearm parts: glass-filled nylon and polycarbonate

Firearm parts have to hold up under friction, heat, cold, compression and vibration. Plastimold has experience molding glass-filled nylon for stocks, grips, rails and housings that need stiffness and strength, and polycarbonate for clear or impact-resistant parts. We also overmold rubber or TPE grip surfaces onto rigid substrates and mold plastic over metal inserts.

Processing discussions include fill behavior, cooling, shrinkage, fiber orientation, and the tolerances that matter at the interface. The correct choice depends on loads, temperature, contact surfaces, friction, cosmetics, and assembly method. Plastimold can review molding conditions and inspection points with the OEM before release.

Work Flow

DFM

Review geometry, interfaces, loads, appearance, and assembly context before tooling. Engineers look for uniform walls, practical draft, ribs, shutoffs, and fastening features.

Tooling

Gate strategy, runner balance, cooling, venting, ejection, texture, and parting lines are evaluated against the resin and cycle before the mold is cut.

T1 / FAI

After mold prove-out, molding parameters and inspection points are documented around the critical dimensions and characteristics that matter most.

Production

Production support continues through first articles, process refinement, repeat runs, packaging, and fulfillment scheduling. CNC can complement molded parts when a machined element is needed.

Quality & CNC support

Quality systems start with clear requirements, controlled revisions, traceable approvals, and inspection plans matched to the part. Review quality systems and compliance information for AS9100, ITAR, and CAGE context. Plastimold also manufactures complete firearms utilizing both CNC machined parts and injection molded components. We assemble, package, and ship to your customer. Firearms and tactical customers include META Tactical, for whom we mold the META Tactical MX-1 chassis system. For machined metal parts, including barrels and receivers, see firearms CNC machining.
