RIM Manufacturing for Large Plastic Parts Without High Mold Cost
1.Produce large plastic housings without expensive injection molds
2.Shorten development cycles for low-to-medium volume production
3.Support parts up to 2500 mm with smooth cosmetic surfaces
4.Ideal for medical, robotics, EV, and industrial equipment enclosures
Choose the Right RIM Process
PUR RIM
Reduce tooling cost for large cosmetic housings
Better suited for thicker-wall lightweight parts
Typical wall thickness: 3–12 mm
Lower tooling investment for low-volume production
Smooth Class-A surfaces suitable for painted exterior parts
Suitable for parts up to 2500 mm+ depending on geometry
PDCPD RIM
Improve impact resistance in harsh operating environments
Better chemical, moisture, and corrosion resistance
Typical wall thickness: 3–8 mm
Higher structural rigidity for heavy-duty applications
Excellent outdoor durability and UV performance
Lower material density than many metal alternatives
Suitable for large industrial structural components
Lower Your Large-Part Production Cost
Built for Large Low-Volume Parts
PUR and PDCPD RIM help you produce large plastic parts faster with lower investment and greater design flexibility
DFM for Thick Sections
You avoid sink, stress, and deformation by designing for uniform flow and controlled wall thickness.
Lower Mold Investment
Reduce tooling cost for low-to-medium volume production projects
Cosmetic Surface Options
Suitable for painted exterior housings and customer-facing components
Applications for PUR & PDCPD RIM
When metal fabrication becomes too heavy or injection molding becomes too expensive, PUR and PDCPD RIM help you manufacture large durable components with greater production flexibility
RIM Parts Built for Large, Complex & Low-Volume Production
You get lightweight, durable, and cosmetic-ready components with lower tooling investment and faster production flexibility.Premium Rapid & Mold supports your project from prototype to production with integrated RIM manufacturing, finishing, and assembly solutions.
Proven In Real Production
Discover how your industry peers reduced tooling costs, accelerated validation, and improved part durability with PUR RIM and PDCPD molding
Traditional injection molding tooling was too expensive for our low-volume medical device program. Premium Rapid & Mold helped you reduce tooling costs with PUR RIM whilst still achieving the cosmetic finish and structural performance required for production. Faster tooling revisions also helped you accelerate product validation without delaying launch.
Managing separate suppliers for molding, machining, and painting created constant delays during development of our EV charging enclosure. Premium Rapid & Mold simplified the process with integrated RIM production, CNC trimming, painting, and assembly support. You could move from prototype to bridge production much faster with fewer supplier coordination problems.
Our previous plastic covers cracked under heavy outdoor operating conditions, and fabricated metal assemblies were too heavy for our equipment platform. Premium Rapid & Mold recommended PDCPD RIM to improve impact resistance whilst reducing overall component weight. The final parts performed better in harsh environments and simplified our low-volume production process.

Frequently asked questions
PUR RIM is suitable when your project requires:
- Lower tooling investment
- Large-part manufacturing
- Faster tooling modifications
- Low-volume production
- Cosmetic Class-A surfaces
- Lightweight structural components
Compared with traditional injection molding, PUR RIM helps you reduce tooling risk during prototype and bridge-production stages.
PDCPD molding gives you high impact resistance, strong chemical resistance, and excellent durability for harsh industrial and outdoor environments.
You can use PDCPD for:
- Agricultural machinery covers
- Construction equipment panels
- Heavy-duty vehicle components
- Outdoor structural housings
It is also a practical alternative to fabricated metal structures when you need to reduce weight and corrosion risk.
Yes. You can move from prototype validation to short-run production through one manufacturing workflow.
Premium Rapid & Mold supports:
- Prototype tooling
- Bridge production
- Low-volume manufacturing
- CNC secondary machining
- Painting and assembly support
This helps you avoid changing suppliers between development and production stages.
Your RIM components can be supplied with:
- Painting
- Textured surfaces
- CNC trimming
- Insert installation
- Assembly preparation
- Cosmetic finishing support
Surface finishing options depend on your application, cosmetic requirements, and production volume.
You can receive our engineering support before production begins, including:
- DFM analysis
- Structural optimisation
- Material recommendations
- Manufacturing feasibility review
- Tooling evaluation
This helps you identify potential molding, assembly, and dimensional issues early whilst reducing costly tooling revisions during production.
