Custom Large Plastic Covers, Built for Your Equipment
Plasticpartsmfg manufactures oversized plastic covers and enclosures for industrial machinery, automated systems, medical equipment, transportation, and other demanding OEM applications.
From single-unit prototypes to contract manufacturing, we bridge design and production with process options matched to your part geometry, materials, and operating requirements.
Large-format covers engineered around your equipment, mounting points, and production needs.
1–5 units
Prototype quantities for fit and design validation
Three stages
Prototyping, low-volume bridge runs, and contract manufacturing
CAD to production
Manufacturing based on your CAD files and engineering drawings
Manufacturing capabilities
Choose a process that fits the part
We select production methods around geometry, material, quantity, structural requirements, and cost targets. Explore the common options.
Thermoforming and vacuum forming
Well suited to large, thin-walled covers and housings when lower tooling costs are important. Part design can be tailored to the required surface area, contours, and mounting interfaces.
CNC machining
A strong option for thick-walled, heavy-duty covers that need high dimensional accuracy or complex mounting features machined into the part.
Plastic fabrication
For large, angular designs, sheet materials can be cut, bent, and bonded to create structural shells and custom enclosures.
Rotational molding
Suitable for large, hollow, complex shapes that call for uniform wall thickness and high impact resistance.

Material selection
Match material performance to the application
Material selection affects impact performance, appearance, chemical resistance, heat behavior, and finishing options. We work with a range of engineering plastics for industrial covers.
| Material | Key characteristics |
|---|---|
| ABS | Excellent impact resistance; easy to finish and paint. |
| PC (Polycarbonate) | High transparency, extreme impact strength, and heat resistance. |
| HDPE | Chemical resistance, durability, and low cost for large shells. |
| PP | Flexibility, fatigue resistance, and chemical stability. |
| PVC | Rigid, flame retardant, and cost-effective for enclosures. |
| PMMA (Acrylic) | Superior optical clarity for inspection windows and covers. |
Design for fit and performance
Engineering details that matter at large scale
Large surface areas and equipment interfaces make structural stability and assembly critical. We work with your team to balance rigidity, weight, manufacturability, and fit.
- 1
Wall thickness: Control thickness for structural rigidity without unnecessary weight.
- 2
Draft angles: Account for clean part removal in thermoforming and molding processes.
- 3
Mounting interfaces: Integrate inserts, bosses, and ribbing for secure attachment to equipment.
- 4
Tolerances: Prioritize precision at critical mounting points while allowing for material expansion across large surfaces.
Configure the cover around your requirements
Share your dimensions, operating environment, and assembly needs so the design can account for key performance criteria.
Size and wall thickness
Specify overall dimensions and preferred thickness or rigidity targets.
Impact and environment
Describe impact, chemical, UV, or flame-retardant requirements.
Transparency and finish
Choose transparent or opaque materials and note surface finish needs.
Interfaces and assembly
Identify mounting points, hardware, seals, and other fitment details.
Finishing and quality
Ready-to-assemble components
Secondary operations can help deliver covers closer to your assembly requirements. Parts are manufactured to your CAD files and technical drawings, with dimensional inspections to verify specified tolerances and equipment fit.
Surface finishing
Painting, texturing, and specialized coatings for UV or chemical protection.
Printing and marking
Silk screening or laser engraving for logos, warning labels, and serial numbers.
Assembly
Integration of hardware, gaskets, seals, and mounting brackets.
Bonding
Professional-grade chemical or mechanical bonding for large fabrications.
Production support
From first prototype to ongoing builds
Production can scale with your project, whether you are validating a new design, preparing for market entry, or supporting recurring equipment builds.
-
01
Prototyping
1–5 units to validate design and fitment.
-
02
Low-volume and bridge production
Small batches for pilot testing or market entry.
-
03
Contract manufacturing
Consistent production for ongoing equipment builds.
Inspection and manufacturing review
Dimensional inspections check that covers meet specified tolerances and fit your equipment. Our engineering team can review your files and provide a DFM (Design for Manufacturing) assessment to help optimize cost and performance.
Helpful files to include
CAD files in STEP, STP, IGES, or X_T format, along with engineering drawings and material specifications.
