V. How to Select a Silicone Product Manufacturer
Looking for silicone product manufacturer recommendations? How to choose the right factory (key selection criteria/Siqi/Qunhao).
Check for in-house mold capabilities: Prioritize factories with their own mold workshops;
outsourcing molds often leads to slow modifications and unstable tolerances (Lianyufeng has an in-house CNC mold workshop for independent mold creation and modification; Zhongsheng specializes in custom molds for non-standard, complex shapes).
Check material qualifications: Request test reports in advance for food-grade, anti-static, or specialty materials (Qunhao offers food-grade testing; Milaike offers food-grade platinum-cured silicone).
Check full-chain capabilities: Qunhao handles all processes in-house (no outsourcing or white-labeling); Zhongsheng manages the entire workflow from mold creation to finished product;
Siqi handles formulation, structural design, mold making, and prototyping. Check scale and capacity: Zhongsheng (8 million units);
Qunhao (100+ employees); Siqi (40 experts, 20,000 product types). Check certifications: ISO9001 (Qunhao, Zhongsheng); ISO14001 & SA8000 (Zhongsheng); BSCI (Qunhao); IATF16949 (Dongguan JR Silicone).
Check post-processing: In-house screen printing and spraying offer better control (Lianyufeng handles screen printing and anti-static spraying; Yongchangxing handles spraying).
Check export experience: Zhongsheng (Universal Studios, Disney, Sedex, Fortune 500 clients); Milaike (cross-border trade qualifications); Qunhao (export certifications).
Check MOQ and lead times: Confirm minimum order quantities (MOQ), lead times, and mold ownership in the contract (Qunhao: 3–7 day sample turnaround; Zhongsheng: full-process support).
Ensure compliance: QC (Qunhao: 100% inspection plus spot checks; dimensional inspection via AQL; visual quality checks); Certifications (ISO9001, ISO14001, SA8000, food-grade testing); Traceability (material reports, mold documentation, inspection records).
Tier-based management—categorizing suppliers by sector (Drinkware: Qunhao/Guifeng; Electronics: Zhongsheng; Industrial Seals: Lianyufeng; Precision LSR: Boluo) and optimizing them through quarterly reviews covering delivery times, yield rates, mold ownership, and after-sales responsiveness.
