Choose a silicone supplier, don't just compare prices<\/h2>\n\n\n\n

The true cost of silicone products comes from:Yield, Rework, Lead Time Stability and Lot Consistency<\/strong>The procurement stage is often more cost effective than \"asking for more quotes\". A clear set of evaluation criteria at the procurement stage is often more cost-effective than \"asking for more quotes\".<\/p>\n\n\n\n

12 Procurement Concerns (recommended to be directly into a supplier evaluation form)<\/h2>\n\n\n\n

1) Availability of own factories with key process capabilities<\/h3>\n\n\n\n
    \n
  • Availability of mold machining\/maintenance capabilities<\/li>\n\n\n\n
  • Whether molding, trimming, and inspection are done in the same system<\/li>\n<\/ul>\n\n\n\n

    2) Willingness to do a DFM (manufacturability review)<\/h3>\n\n\n\n

    A good supplier will suggest before opening the mold: draw slope, thin edge, parting line position, risk of groove, etc.<\/p>\n\n\n\n

    3) Source and traceability of materials<\/h3>\n\n\n\n
      \n
    • Ingredient brand and batch records<\/li>\n\n\n\n
    • Availability of material specifications with statement of conformance<\/li>\n<\/ul>\n\n\n\n

      4) Consistency guarantee between samples and mass production<\/h3>\n\n\n\n
        \n
      • Availability of small batch pilot production and process validation<\/li>\n\n\n\n
      • Ability to lock in key parameters<\/li>\n<\/ul>\n\n\n\n

        5) Critical dimensions (CTQ) management<\/h3>\n\n\n\n
          \n
        • Ability to recognize critical dimensions<\/li>\n\n\n\n
        • Whether there are clear test methods and records<\/li>\n<\/ul>\n\n\n\n

          6) Whether the appearance criteria are quantifiable<\/h3>\n\n\n\n
            \n
          • Raw edge height, parting line, color difference range<\/li>\n\n\n\n
          • Clear definition of visible\/sealing surfaces<\/li>\n<\/ul>\n\n\n\n

            7) Real ability of delivery time and capacity<\/h3>\n\n\n\n
              \n
            • sampling period<\/li>\n\n\n\n
            • Mass Production Scheduling and Material Availability<\/li>\n<\/ul>\n\n\n\n

              8) Communication efficiency and engineering interface capabilities<\/h3>\n\n\n\n
                \n
              • Ability to quickly understand drawings and working conditions<\/li>\n\n\n\n
              • Whether actionable changes can be suggested<\/li>\n<\/ul>\n\n\n\n

                9) Is the offer structure transparent<\/h3>\n\n\n\n
                  \n
                • Mold fee, unit price, secondary process, inspection, packaging<\/li>\n\n\n\n
                • Availability of MOQ and Step Pricing<\/li>\n<\/ul>\n\n\n\n

                  10) Quality Exception Handling Mechanism<\/h3>\n\n\n\n
                    \n
                  • How to determine defective products<\/li>\n\n\n\n
                  • Corrective action and review are in place<\/li>\n<\/ul>\n\n\n\n

                    11) Packaging and shipping standards<\/h3>\n\n\n\n
