Bakelite (phenolic resin) is widely used in gas spring bushings, electrical insulators, and automotive parts due to its high heat resistance and hardness.

However, its quality is highly sensitive to raw materials, molding process, and post-treatment.

At Hitech, we take every step to ensure our Bakelite products remain stable, durable, and defect-free. Below are the key measures we use to maintain consistent quality.

✅ Strictly Control Raw Materials: Eliminate Hidden Dangers at the Source

• Premium Raw Material: We use high-quality phenolic resin from Chang Chun Plastics (Taiwan), a leading supplier known for its stable molecular structure and reliable performance.

• Batch Consistency: Every incoming batch is inspected for moisture content and resin purity to eliminate brittleness, discoloration, or dimensional instability.

• Controlled Storage: Our warehouse maintains 24-hour constant temperature storage to prevent moisture absorption, which could cause bubbles or defects during molding.

• Additive Control: We use standardized curing agents and fillers to ensure uniform hardness and wear resistance across all products.

⚙️ Optimize Injection Molding Process: Reduce Defect Rate

• Temperature Control: We maintain precise mold and barrel temperatures (160–190°C) to avoid charring, under-curing, or brittleness.

• Pressure & Speed: Injection pressure and hold time are fine-tuned to eliminate internal voids, sink marks, or incomplete filling.

• Curing Time: We follow strict post-mold curing protocols to ensure full cross-linking, maximizing heat resistance and structural integrity.

🧹 Precision Post-Processing: Improve Dimensional Accuracy and Surface Appearance

• Deburring: Sharp edges are removed with precision tools to maintain tight tolerances, avoiding dimensional deviation caused by over-sanding.

• Moisture-proof Packaging: Finished products are stored in dry, sealed packaging to prevent swelling or dimensional changes from humidity.

• Protective Treatment: Critical parts (e.g., gas spring bushings) receive a thin protective coating to enhance wear resistance and extend service life.

📏 Full Inspection & Batch Traceability: Quality Traceable

• Key Dimensions Check: Critical tolerances (inner/outer diameter, height) are verified for every batch to meet customer specifications.

• Performance Testing: Samples undergo heat resistance, compression, and impact tests to confirm compliance with industry standards.

• Traceability: We record raw material batch, molding parameters, and test results for every production run, ensuring full traceability

💡 Summary

At Hitech, stable Bakelite quality stems from high-grade raw materials, standardized production processes and strict quality testing. We follow stringent material selection and comprehensive inspection protocols to deliver Bakelite products that satisfy top-tier requirements for industrial, automotive and electronic use.
