From Prototyping to Production
Moving from initial concepts to market-ready products, Bilichitech’s vacuum casting services offer cost-effective
solutions for your product development.
Certified Quality Control and Testing
Bilichitech operates as an ISO 9001:2015, ISO 13485, ISO14001:2015, and IATF 16949:2016 certified vacuum
casting manufacturer. Our quality control covers three critical areas:
Dimensional Testing
Dimensional testing uses CMM, digital calipers, height gauges, and micrometers to verify tolerances, geometric positioning, hole diameters, wall thickness, and fit dimensions.
Visual Inspection
Visual inspection employs magnifiers, roughness testers, and color charts to detect surface defects including bubbles, scratches, dents while ensuring color consistency and surface finish quality.
Paint Adhesion Testing
Paint adhesion testing validates coating bond strength, durability, and thickness uniformity for all finishing requirements.
What's Urethane Casting Process?
Urethane casting, also called vacuum casting, draws liquid urethane into a mold to create plastic and rubber parts with intricate geometries. Here are the 3 steps.
Master Patterns
The master pattern replicates the final casting parts, determining product quality. Create it via CNC machining or 3D printing. 3D printing is faster and cheaper, but CNC offers tighter tolerances. Design considerations include draft angles and wall thickness.
Solicone Mold Casting
Pour liquid silicone rubber around the master pattern. Most cure in ovens, while RTV molds cure at room temperature. After a few hours, cut along the parting line to remove the master, creating a silicone mold ready for casting.
Urethane Pouring and Finishing
Mix liquid polyurethane resin and pour into molds under vacuum to prevent air bubbles and defects. Curing takes 30 minutes to 2 hours depending on material and size. One mold produces 1-10 copies daily. Cast urethane parts may require post-processing
