Precision Silicone Molding: From Flash-Free to Overmolding

Flash-Free Precision Molding:

Our 250T Xin Jinli compression presses enable zero-flash curing for complex geometries, eliminating secondary trimming and ensuring consistent, high-quality finishes.

High-Tolerance Overmolding:

Achieving ±0.05mm strict tolerances, we specialize in overmolding silicone onto metal/plastic inserts for critical sealing and assembly applications.

Rapid In-House Tooling:

Supported by 170+ CNC centers, we machine ultra-precise silicone molds in-house, cutting tooling lead times from weeks to days.

Specialized Silicone Solutions

Medical Silicone Molding :

Manufacturing highly clean, tear-resistant, and biocompatible silicone components like biopsy valves and surgical seals.

Custom Seals & Gaskets:

High-performance silicone and rubber molding for automotive and industrial fluid management, offering extreme temperature resistance.

Silicone-to-Metal Overmolding:

Combining our CNC machined metal inserts with flexible silicone to create durable, waterproof, and vibration-dampening assemblies.

Quality Control: Non-Contact Metrology for Flexible Components

Measuring elastomers accurately requires advanced technology to prevent part deformation during inspection.

Keyence IM-7010 Vision System:

High-speed, non-contact optical inspection suitable for non-contact measurement of soft silicone parts and dimensional verification based on approved inspection criteria without physical distortion.

Tianrui RoHS Analyzer:

100% material verification for biocompatibility and environmental safety.

Eliminating Variance in Elastomer Manufacturing

Precision Tooling & Flash Control

Silicone's low viscosity demands precision tooling. During our standard 4-week prototyping phase, we optimize mold parting lines and lock in exact curing temperatures. This strict ECO management helps reduce batch-to-batch variation and flash risks through tooling control, molding parameters, and inspection.

Advanced Vision Verification

Flexible parts are notoriously difficult to measure. We utilize non-contact Keyence Vision Systems and Hexagon CMMs to verify critical sealing dimensions, ensuring your 500th part performs exactly like the first.

Strict Material Compliance

We provide comprehensive lot traceability for every batch of elastomer. Raw materials are rigorously verified via our in-house Skyray EDX1800B Spectrometers to support RoHS documentation and material verification based on project requirements for the global 3C and automotive markets.

Design Guidelines for Silicone Compression Molding

Design Feature	General Recommendation	Aizhuo Milling Capability	DFM Optimization Tips
Wall Thickness	1.0mm - 3.0mm (Uniform)	We design specialized mold venting channels to prevent trapped air and help improve thin-wall curing stability.	Maintain consistent thickness to ensure even heating and curing. Avoid abrupt changes in thickness.
Undercuts	Highly flexible, easily demolded	Unlike rigid plastics, silicone's elasticity allows us to mold complex internal undercuts without expensive side-action cams.	Design undercuts with smooth radii to prevent tearing during the demolding process.
Tolerances	Standard ±0.05mm	Because we machine our molds on highly rigid HAAS & Mazak CNCs, we control flash to an absolute minimum.	Specify tighter tolerances only on critical sealing surfaces to keep tooling costs highly economical.
