Medical Device Parts
Custom plastic parts for medical equipment, device housings, internal supports, protection parts and assembly components.
Industrial Molded Parts
Molded components for machinery, instruments, equipment, sealing systems and industrial product assemblies.
Insert & Assembly Parts
Plastic components designed for integration with rubber, foam, adhesive materials, metal inserts or other functional structures.
Custom OEM Projects
Drawing-based and sample-based production support for customers who need reliable molded parts and long-term supply.
Common Pain Points in Injection Molding Projects
Many molding problems are caused by poor early-stage review. Material mismatch, weak tooling design, unstable molding parameters or unclear tolerance control can increase cost, delay delivery and create quality risks.
Problems Customers Often Face
- Warpage, shrinkage or deformation after molding
- Flash, sink marks, weld lines or poor surface appearance
- Unstable dimensions between samples and mass production
- Wrong material selection for strength, heat or chemical resistance
- Poor fit with foam, rubber, adhesive or electronic components
- Tooling changes after sampling, increasing cost and lead time
- Supplier cannot support engineering review and production control
Injection Molding Capability with OEM Project Support
Sanken combines injection molding with material converting, die cutting and assembly support. This helps customers reduce supplier complexity when molded plastic parts need to work together with foam, rubber, adhesive tape, protective film or insulation materials.
