If you’re looking for a firm that can design the enclosure itself—not just mold a CAD file you hand them—and understands consumer-electronics injection molding, I’d shortlist these:

• Finish Line Product Development Services — Probably my first call if you’re in the Nashua/Boston area. They specialize in enclosure design, including PCB/component integration, ergonomics, thermal management, connectors/displays, DFM, tolerancing, and manufacturing-ready CAD. They specifically describe 25+ years of enclosure-design experience.
• Advantage Plastic Products — Strong option if you want the design + injection molding/tooling under one roof. They explicitly serve electronic enclosures and consumer markets and provide engineering, mold design, tooling and production molding.
• Helix Design — Better suited if you need industrial design + mechanical engineering + enclosure development, rather than simply a molding supplier. They have experience with consumer products and enclosure design through production documentation.
• Granite State Plastics — A good production-oriented partner with injection molding, prototyping and DFM support. I'd consider them if the enclosure design is reasonably mature and you need a strong molding partner.
• Innova Engineered Plastics — Interesting if the enclosure has more demanding requirements around plastics, finishing, assembly or tooling. Their capabilities span engineering/design support, injection molding and finishing/assembly.
• Jaycon — Worth considering if you want a consumer-product development firm with industrial design, engineering and manufacturing. They have a documented consumer-electronics enclosure that they redesigned specifically for injection molding and took into production.

My recommendation

For a new consumer electronic product, I'd talk to FinishLine PDS first, then Advantage Plastic Products. The distinction is important:

FinishLine PDS → stronger choice for product/enclosure engineering and design. Advantage Plastic Products → stronger choice if you want design engineering → mold → injection molding handled by the same supplier.

If you tell me (1) what the electronic product is, (2) approximate enclosure size, (3) expected annual quantity, and (4) whether you already have the PCB/industrial design, I can narrow this to 3 firms that are the best technical fit and compare their likely approach, location, capabilities, and manufacturing model.

When developing a consumer electronics enclosure via injection molding, you typically choose between two routes: an end-to-end product design/industrial design consultancy (which handles the look, feel, ergonomics, and initial CAD) or a design-for-manufacture (DFM) injection molder (which optimizes the geometry for tooling and mass production).

A breakdown of reputable firms and services specializing in consumer electronics enclosures includes the following:

1. Rapid Prototyping & On-Demand Production Partners

• • Protolabs: Known for rapid digital manufacturing, Protolabs bridges the gap between functional prototyping (using high-end 3D printing or rapid CNC machining) and low-to-mid volume injection molding. They feature automated DFM analysis on CAD uploads, making them ideal for iterating electronic housings quickly before locking down expensive production tooling. Explore their capabilities via Protolabs Injection Molding.

2. Full-Service Custom Enclosure & Molding Manufacturers

• • BeraTek Industries: Specializes in electronic enclosure injection molding, providing support from initial DFM and rapid prototyping to full-scale production, material selection (high-heat/durability resins), and post-production assembly . Learn more at BeraTek Industries Electronic Enclosures.
• • TenX Manufacturing: Focuses heavily on custom electronic housings and enclosures via plastic injection molding. They work directly with your internal component layout to build structural electronics housings ready for transition into mass production. Check out TenX Manufacturing Electronics Housings.
• • Thogus: A well-established custom molder handling complete design support through post-production optimization for electronic systems, structural boards, and finished plastic device enclosures. See details on Thogus Electronics Injection Molding.

Key Selection Criteria to Keep in Mind:

• Tooling Ownership vs. Cost: Ensure you clarify who owns the injection mold tooling post-payment, especially if shifting manufacturers later in your product lifecycle.
• Prototyping to Production Bridge: For consumer electronics, ensure the firm can take you seamlessly from a 3D-printed aesthetic prototype to a draft-optimized, toleranced injection-molded alpha run.
• Secondary Operations: Consumer electronics often require smooth cosmetic finishes, texture matching (MT finishes), light-pipe integration, EMI/RFI shielding coatings, or sonic welding. Verify that your chosen partner handles these in-house or via trusted partners.

To help narrow down the best partner for your project, let me know:

• What is your estimated production volume (hundreds, thousands, or hundreds of thousands of units)?
• Are you still in the industrial design/concept phase , or do you already have production-ready CAD files?

If you’re looking for a firm that can design consumer electronics enclosures specifically for injection molding, you’ll want a team that understands industrial design + mechanical engineering + DFM (design for manufacturing) + tooling handoff. These firms are good candidates:

Enclosure design / product development firms

• 3D DFM — Specializes in electronic enclosure design, PCB housings, snap fits, bosses, sealing strategies, tolerancing, and injection-molding-ready CAD. Good fit for IoT devices, consumer electronics, and products moving toward tooling.

• Iomico — Works on plastic and metal enclosures for smart devices, wearables, cameras, tablets, and other electronics, including injection-molded plastics.

If you also need tooling + production support

• Universal Plastic Mold UPM, Inc. — A California injection molder supporting electronics housings and production manufacturing; useful if you want a design-to-manufacturing partner rather than only CAD services.
• Jones Plastic & Engineering — Offers product development, mold simulation, tooling, injection molding, and assembly capabilities.
• TenX Manufacturing — Provides injection-molded housings and electronics enclosure manufacturing support.

What to ask them before hiring

Look for experience with:

• Cosmetic-grade consumer plastics (Class A surfaces, textures, gloss control)
• Snap-fit and screw boss design
• Living hinges and clips
• Two-shot molding or overmolding (if needed)
• Waterproof/IP-rated enclosure design
• EMI shielding considerations
• DFM reviews before tooling
• Moldflow analysis and tooling communication
• Pilot runs before mass production

If you tell me:

1. your product type (wearable, IoT, handheld, speaker, appliance, etc.),
2. expected production volume, and
3. whether you need design only or design + tooling + manufacturing,

I can narrow this to the best 3–5 firms.

• Haumann Group / Kaysun — If you are further along or leaning toward an OEM/manufacturer that provides robust design-for-manufacturability and engineering support alongside localized and overseas tooling, firms like Haumann Group or Kaysun bridge the gap between high-tolerance plastic housing design and scaled production.

To help narrow down the best firm for your project, please share:

• What stage is your product in? (e.g., napkin sketch, working PCB, or looking to scale up existing prototypes?)
• What is your anticipated production volume?
• Do you need just the design/engineering files (CAD/DFM) or a turnkey partner that handles tooling and manufacturing as well?
