FAQ
Q1: How do you control dimensional consistency and eliminate flash for precision sealing parts?
Ans: We control dimensional consistency by utilizing advanced multi-cavity tool balancing, optimized cold runner venting structures, and strict PLC curing parameters. This minimizes flash and batch-to-batch dimensional variation, strictly maintaining compliance with ISO 3302-1 M1/M2 precision standards.
Q2: What silicone materials do you commonly recommend for industrial sealing applications?
Ans: For most industrial sealing projects, we primarily recommend high-performance VMQ silicone compounds due to their excellent thermal stability, weather resistance, elasticity, and long-term sealing reliability. Depending on the operating environment, we can also optimize material hardness, compression set performance, and tear strength to support applications involving dustproofing, waterproofing, vibration isolation, and outdoor exposure.
Q3: What is your capability regarding low compression set performance?
Ans: We custom-formulate post-cured silicone elastomers that optimize cross-linking density, achieving a low compression set of under 15% under prolonged mechanical compression and high-temperature testing. This prevents material relaxation and guarantees zero leakage over long lifecycles.
