Molded Plastic Enclosures Manufacturer

We specialize in custom plastic enclosures, offering you the flexibility to design a plastic enclosure that represents your company brand, including requirements such as styling, size parameters, color preferences, material choices, and IP rating specifications. As a specialized manufacturer of custom enclosures, we can take care of the entire production process, from mold design and production to plastic enclosures.

Getting your custom plastic enclosure is simple — send us your drawing or sample, and we’ll handle mold design, DFM, quoting, and manufacturing. Contact us anytime via our website, email, or phone to get started.

Custom Plastic Enclosure to Fit Your Application

Plastic enclosures come in many forms, such as handheld housings, sealed boxes, PCB enclosures, snap-fit covers, multi-part shells, DIN-rail cases, and ergonomic units. At Flexiparts, we tailor the enclosure’s geometry, internal structures, fastening method, and material to meet your functional and installation needs, ensuring proper heat dissipation, stiffness, assembly, and protection for your components.

Design Suggestions for Custom Plastic Enclosures

When designing a custom plastic enclosure, consider functionality, assembly, and durability. Select materials for your environment and mechanical needs and ensure proper wall thickness, ribs, and supports for stiffness. Plan fastening methods, ventilation, heat dissipation, and protection against moisture, chemicals, or UV. Include any special features such as gaskets, drainage, or shielding to reliably safeguard your components.

Manufacturing Process

Available Material

Every custom plastic enclosure application is unique. When selecting the plastic for your plastic enclosure, it is important to evaluate whether the plastic’s quality aligns with your specific usage requirements, ensuring that it keeps your electronics safe in normal environments. Using a variety of types, colors, and grades of materials, we can meet your custom plastic enclosure needs.

Common materials for plastic housings and enclosures are:

ABS: Glossy, UL 94HB, UL 94V0
PA: Wear-resistant, great electrical insulator
PC: Transparent, UV-resistant, high-strength
PC+ABS: UL 94 V-0, high impact strength
PMMA: Transparent, light-weight, high-light transmission
HIPS (High impact polystyrene): UL 94HB, UL 94V0, high impact strength

FAQ of Plastic Enclosure Box

What materials are suitable for transparent enclosures?

Polycarbonate (PC) offers high impact resistance and clarity, while acrylic (PMMA) provides excellent optical clarity but is less impact-resistant. PC/ABS blends can also be used if partial transparency is needed.

I need special features like inserts, gaskets, or transparent windows – is that possible?

Absolutely. We support threaded inserts, insert molding, gasket channels, and clear areas for displays or indicators.

How can I make sure my enclosure fits my components perfectly?

We optimize internal layouts, mounting points, wall thickness, and snap-fit features to ensure your PCBs, connectors, sensors, and other parts fit securely without compromising strength.

What if I’m unsure about materials or design?

Our engineers review your CAD and provide DFM recommendations, helping you choose between ABS, PC/ABS, or other materials to balance cost, strength, and environmental requirements.

Will a custom plastic enclosure withstand harsh outdoor conditions?

Yes. With years of experience, we design enclosures for strength, rigidity, and protection. They can meet IP ratings and use UV-stabilized or fire-retardant ABS, making them reliable in sun, rain, heat, oil, and other harsh conditions.
