Vacuum Casting Stations
Dedicated vacuum casting services for small and mid-size plastic parts, using silicone mold casting techniques with a diverse range of materials mimicking plastics and rubber.
Paint Shop
High-quality paint shop to achieve the desired colour and finish for prototyping and production.
Assembly Stations
Child part assembly and validation with gap and flush checks.
Polyurethane Materials
Diverse imported materials mimicking ABS, PP, PC, PA, POM, HDPE, etc.
Elastomeric PU for Rubber-Like Flexibility
Ideal for seals, soft-touch surfaces, and overmoulded areas.
Flame-Retardant PU Grades
UL94-V0 certified PU material to for functional testing and regulatory compliance.
Complex Features with High Accuracy

Short Lead Times for 10–100 Units
Part supply initiation in 7 – 10 days, enabling faster product testing and validation.
Overmoulding and Insert Integration
Unlike 3D Printing and Machining, insert-moulding and over-moulding are possible with strong adhesion between inserts & PU.
Consistent Quality with Stage-Wise QC
Controlled process and inspection at every stage ensure dimensional and functional accuracy for end-use or validation parts.
Rapid Prototyping + Low-Volume Manufacturing
Precision Polyurethane Parts that Perform Like Production-Grade Plastics
As a specialist vacuum casting company, Marcopolo’s dedicated Vacuum Casting & Reaction Injection Moulding (RIM) facility delivers end-use-quality components that mimic ABS, PP, PA, PC, POM and other engineering plastics, at a fraction of the cost and lead time of Injection Moulding. Our vacuum casting services are ideal for functional testing, product demonstrations, and low-volume production runs.

Testimonials
What Our Clients Say?
Need 10 to 100 Parts Without Expensive Tooling?
Get high-performance, functional parts that look and feel like final production
through our vacuum casting services and reaction injection moulding capabilities
without long lead times or steel mould costs.
What is vacuum casting used for?
Vacuum casting is ideal for producing functional prototypes and low-volume production parts using polyurethane materials that mimic engineering plastics like ABS (Acrylonitrile Butadiene Styrene), PP (Polypropylene), and PC (Polycarbonate).
It’s commonly used in industries such as automotive, medical devices, and electronics for fitment testing, functional validation, and market-ready samples, especially when tooling costs are prohibitive.
Can vacuum casting be used for end-use parts?
Yes! Vacuum casting is often used for end-use parts in small quantities, especially when hard tooling isn’t justified yet. Many clients use these parts for trade shows, pilot programs, or even field testing, thanks to their realistic look, feel, and performance.
How do vacuum casting and RIM compare to injection moulding?
Unlike injection moulding, vacuum casting and RIM don’t require expensive steel tools, which makes them ideal for prototyping and low-volume runs. They allow for faster iterations, lower upfront cost, and material flexibility, while still delivering production-like quality and performance.
What is Reaction Injection Moulding (RIM)?
RIM is a low-pressure moulding process where two liquid polymers, polyol and isocyanate, mix and react inside a mould to form rigid or flexible polyurethane parts. It’s ideal for producing large, lightweight components with production-grade performance.
What is silicone Mould casting and when should I use it?
Silicone Mould casting is a flexible and cost-effective process for producing small batches of high-detail parts in production-equivalent materials. It is ideal for functional prototypes and small-batch production when you need realistic material performance without hard tooling .
What are the benefits of your vacuum casting services?
Our vacuum casting services deliver bubble-free, production-equivalent parts with excellent mechanical properties in 7-10 days. As a leading vacuum casting company, we support complex designs and material variations that mimic engineering plastics.
What is Reaction Injection Moulding (RIM) and how does it differ from vacuum casting?
Reaction Injection Moulding (RIM) is a low-pressure manufacturing process ideal for producing large, lightweight components up to 2 metres in size as a single piece. While vacuum casting is best suited for small to medium-sized parts made using silicone moulds, RIM is the preferred solution for larger and more complex single-piece components.
Why choose Marcopolo for vacuum casting services in India?
Marcopolo is a trusted vacuum casting company with 25+ years of experience, in-house facilities, and end-to-end support from silicone mould casting to assembly.
What is vacuum casting best used for?
Vacuum casting produces parts in production-equivalent materials, suited for functional prototypes, pilot batches, and field testing before committing to full production tooling.
Do you offer services across India?
Yes. Our silicone Mould casting and reaction injection moulding services are available pan-India, with export capability to international clients as well.
How does RIM compare to injection Moulding for low volumes?
RIM avoids tooling investment, making it the faster, lower-cost route for low volumes and large single-piece parts. Injection moulding becomes more cost-effective as volumes scale up, which is why Marcopolo offers both, so you move to the right process as your program grows.
