What information do you have to prepare? (You can do this 10 minutes before you start customizing.)
Before looking for a silicone products factory, organize the following information first, communication will be much faster:
- Product Use: Sealing, waterproofing, dustproofing, cushioning, keying, overmolding, etc.
- working environment: Temperature range, exposure to oil/alcohol/solvents/acids/alkalis, prolonged outdoor use.
- Structural information: 2D drawings (PDF/DWG) or 3D (STEP/IGES), critical dimensions and tolerances.
- Target performance: Hardness (Shore A), tensile, resilience, abrasion resistance, flame retardant, etc.
- Appearance requirements: Color, surface texture, whether printing/oil spraying/laser engraving is required.
- Annual usage and delivery time: Determine the mold solution and unit price range.
The more complete the information, the faster the proofing; but even without drawings, it is possible to work backwards from samples or sketches.
Standard customization process: from drawing to mass production (it is recommended to advance in this order)
1) Requirements Identification and Manufacturability Review (DFM)
The factory will focus on looking at it:
- is or isn'tThin edges, sharp corners, deep cavitiesand other locations that make mold release difficult.
- Whether the sealing parts meet thecompression ratiotogether withgroove fit.
- Are the tolerances reasonable: too tight can lead to higher costs, too loose can affect assembly and consistency.
(2) Material and formula selection
Common Choice Ideas:
- General Silicone: Temperature and weather resistant, suitable for most consumer electronics and appliance parts.
- High tear/high resilience silicone: Suitable for structures with frequent assembly or high forces.
- Oil/chemical resistant materials(e.g. FKM, etc.): Suitable for oil, fuel and solvent environments.
3) Mold program determination (the most critical step before opening the mold)
It will be decided:
- Number of cavities, gate locations, venting solutions
- Mold Steel and Life Expectancy
- Whether secondary processes are required (gluing, oiling, printing, etc.)
4) Proofing (T0/T1) and size confirmation
Proofing common output:
- sample
- Dimensional measurement report (critical dimensions)
- Material/Color Confirmation
5) Pilot production and process validation (small batch)
The goal is not to "do more" but to validate:
- Yield and Appearance Stability
- Assembly and sealing performance
- Reproducibility of key process parameters
6) Mass production and quality inspection
Commonly used control points in the mass production phase:
- Incoming Material Inspection (Adhesives/Accessories)
- First article confirmation, inspection
- Shipment inspection (size/appearance/functionality/packaging)
6 Factors Affecting Delivery Time and Cost
- Whether the drawings are clear and key dimensions are labeled
- Whether special materials or certified documents are required
- Mold complexity and number of cavities
- Appearance process (oil spraying, printing, hand oiling, etc.)
- Number of test items and standards
- Packaging and Shipping Requirements
Frequently Asked Questions (FAQ)
Q1: Can I do it with only samples and no drawings?
Yes. Usually a mapping modeling is done first, and then a proof is made to confirm.
Q2: How long does it take to proof?
Related to the complexity of the mold. Well-documented projects with simple structures are usually faster.
Q3：How to avoid "sample is OK, but mass production is unstable"?
It is recommended to do a small batch trial production after confirming the samples to fix the key parameters, inspection points and assembly methods.
