Plastic enclosure molding service

We are a specialized custom plastic housing manufacturer, engineering and producing the complete protective shells for your electronics, devices, and industrial products. We serve as your single-source, integrated partner, managing the entire journey from initial concept and structural design to precision molding, finishing, and final assembly. We don't just supply parts; we deliver fully realized, ready-to-integrate housing sub-assemblies that seamlessly fit into your production flow.

Our Service: Comprehensive Housing Solutions

We provide a start-to-finish service that consolidates your supply chain and ensures perfect execution:

Design & Engineering: Collaborative industrial design, detailed 3D CAD, and rigorous structural analysis (DFM/DFA) to optimize your housing for performance, aesthetics, and manufacturability.

Precision Manufacturing: In-house tool fabrication and high-volume injection molding of all housing components (cover, base, bezels, buttons, internal brackets) under one roof.

Full Assembly & Integration: We add the highest value through our vertical assembly services: ultrasonic welding, hardware installation (inserts, PEM studs), gasket/seal application, and even the installation of your PCBs or internal components to create a turnkey module.

Engineered for Performance, Usability, and Manufacturability

We design housings that are structurally sound, user-friendly, and cost-effective to produce. Every element is purpose-driven:

Robust Shell & Internal Structure: Strategically placed ribs, bosses, and mounting pillars are designed to protect sensitive internal components from impact, vibration, and environmental stress, ensuring long-term reliability.

Secure Joining Systems: Expertise in designing robust connections, from sophisticated snap-fits for tool-less assembly to engineered screw bosses that withstand repeated disassembly, all while maintaining a clean aesthetic.

Environmental Sealing (IP Rated): We design for performance, integrating gasket grooves, managing parting lines, and utilizing overmolding (2-shot) with TPE/TPU to achieve targeted IP ratings for dust and water resistance.

Integrated User Interface: Features for displays, connectors, buttons, ventilation, and audio ports are seamlessly incorporated into the design, considering ergonomics, branding, and regulatory markings (UL, CE).

Material Selection for Specific Application Demands

We guide you to the optimal polymer that balances performance, aesthetics, and cost for your housing's environment:

ABS & PC/ABS Blends: The industry standard for a superior balance of impact strength, dimensional stability, surface finish, and cost. Ideal for consumer electronics, power tools, and medical device housings.

Polycarbonate (PC): For maximum impact resistance, transparency, or high-heat applications. Used in ruggedized equipment, protective visors, and LED lighting housings.

Polypropylene (PP): Excellent for chemical resistance, living hinges, and low-cost durability. Common in laboratory equipment, battery cases, and outdoor consumer products.

Specialty Compounds: We specify materials for specific needs: ASA for superior UV/weather resistance, flame-retardant (FR) grades (UL94 V-0) for electrical safety, and EMI-shielding compounds for sensitive electronics.

Precision Molding & Integrated Assembly: Our Core Advantage

Our true differentiation is the seamless integration of high-precision molding with downstream value-added operations in our facility.

Expert Molding for Housings: We specialize in processes critical for housing quality: achieving Class-A surface finishes, managing complex geometries with tight tolerances, and using multi-cavity/family molds to ensure perfect color and fit across all components.

In-House, Value-Added Assembly Services:

Joining: Ultrasonic welding, vibration welding, and solvent bonding for strong, clean seams.

Hardware Integration: Precision press-fitting of threaded inserts, bearings, and nameplates.

Sealing & Decoration: Installation of seals, precision pad printing, laser etching, and spray painting.

Final Assembly: Kitting, component installation (screens, PCBs, wiring), functional testing, and packaging.

Why Partner with Us? Single-Source Accountability for Your Housing.

We eliminate the friction, risk, and delay of managing multiple suppliers. By providing single-point responsibility from design to delivery, we guarantee fit, function, and quality. Our early and deep involvement through Design for Manufacturing & Assembly (DFM/A) ensures your housing is optimized for performance and efficient production from the very start. We reduce your total cost of ownership and accelerate your time to market.
