DOIT has a complete precision rubber production process. From mold opening, material prep, forming, processing to cleaning, sterilization and auto-packaging, professional equipment ensures stable quality.
DOIT Precision Rubber Products: Complete Production Process & Equipment:
Production line
|
|
DOIT uses dedicated lines for 4 core precision rubber parts, with specialized processes, equipment, personnel and standards. It adopts full-chain production (raw materials to finished products) instead of mixed manufacturing, improving precision, stabilizing quality and reducing defects. Dedicated lines avoid interference via "specialized equipment + standardized processes", cutting redundant steps (mold changing, parameter adjustment, equipment cleaning) to boost efficiency and shorten delivery cycles.

Mold Opening Stage
6 CNC Mold Processing Centers: High precision/efficiency/flexibility; solves poor precision and heavy manual reliance in traditional processing.
1 Japanese Sodick Mirror EDM Machine: Advanced PIKA loop; micron accuracy (Ra≤0.02μm); mirror surfaces without post-polishing.
1 Dimon CNC Mirror EDM Machine: 3-axis linkage; positioning accuracy 0.008mm, repeat accuracy 0.005mm; stable long-term processing.

2 Plunger-Type Rubber Filters: 300-500 mesh filtration; remove raw material impurities.
1 Preforming Machine: Shapes raw materials into semi-finished blanks.
|
|
1 Black + 1 Colored Silicone Mixer: Dedicated for specific colors—prevent mixing/contamination; ensure raw material purity and color stability.
1 Medical Silicone Mixer: Customized for medical-grade; meets requirements, avoids contamination, complies with medical hygiene standards.
2 CNC Silicone Cutting Machines: High accuracy, precise weight control—reduce burrs/tolerances; ensure medical/ordinary silicone product quality.

26 precision O-ring compression molding machines (100-200 tons): Specialized for O-rings; stable clamping force ensures precision forming and mass production.
21 pump/valve seal forming machines (200-500 tons): High clamping force guarantees dense structure and precise seal dimensions.
24 silicone molding machines (100-300 tons): Customized for silicone properties; realize efficient, precise forming.
26 rubber compression molding machines (100-300 tons): Meet ordinary rubber compression needs; suitable for multi-type batch production.
12 medical seal flat compression molding machines (100-200 tons): Comply with medical standards; ensure forming accuracy and hygiene safety.
2 medical liquid silicone injection molding machines (50 tons): Specialized for medical-grade liquid silicone seals; improve forming efficiency and accuracy.

|
Production and processing stage
50 stamping machines: For rubber seal punching; fixed molds, stable pressure (defect rate ≤0.5%); ensure uniform shape/thickness, reduce defects, improve batch efficiency.
10 CNC secondary vulcanization ovens: PID closed-loop temp control + multi-point measurement (fluctuation ±1℃, uniformity ≤±2℃); precise temp control ensures fluororubber/silicone molecular cross-linking, enhances resistance to temp/aging, avoids uneven performance.
5 grinding machines: Grind surface protrusions to form dense layer; improve rubber part wear resistance/sealing, extend service life.
|
|
5?units?automatic deburring machines:?5-10x more efficient than manual; automatically remove burrs/flash—reduce labor costs.
2?units?cryogenic deburring machines:?Liquid nitrogen (-196℃) makes burrs brittle; high-speed abrasive impact removes burrs without damage. Suitable for fragile/precision rubber parts.
|
|
Cleaning and sterilization stage
Ultrasonic Cleaning Machine: Cavitation removes stains (no mechanical friction, defect rate ≤0.1%); gently cleans precision products (e.g., medical silicone), avoids scratches and fine structure damage.
High-Temperature Sterilizer: Physical high-temperature sterilization (no chemicals); kills microorganisms in medical silicone products, high rate, no residues—meets medical safety standards.
|
|
Automated processing stage
Automatic Slitting Machine: CNC positioning (±0.1mm), servo drive. Preset trajectory—avoid manual deviation/errors; improve slitting consistency.
Automatic Packaging Machine: Measurement error ≤±1%, sealing temp fluctuation ≤±2℃, labeling deviation ≤±0.5mm. Auto feeding, measuring, bagging/boxing, sealing, labeling; ensure uniform weight/quantity, tight sealing, neat labels, avoid manual defects, improve efficiency.
