Quality control and testing of silicone products are crucial to ensuring they meet the highest standards for safety and performance. This involves a comprehensive approach that includes strict raw material inspection, management of manufacturing processes, physical property testing, and compliance with industry regulations. At Mitour Silicone, we are committed to maintaining a final product reject rate of less than 2%, backed by our ISO9001, BSCI, and FDA certifications.
To ensure the highest quality silicone products, we partner with trusted suppliers to verify the characteristics of the raw materials used in production. Key steps include:
Supplier Verification: We request test reports for silicone raw materials, ensuring compliance with FDA, LFGB, RoHS, REACH, and SDS standards.
Incoming Inspection: Upon arrival at our facility, raw materials undergo rigorous checks before storage, ensuring only high-quality materials are used in production.
Once production is scheduled, our mixing technicians prepare silicone colors according to material specifications. The process involves:
Test Block Creation: After mixing, a test block is produced, and inspectors compare its color and hardness against specified tolerances to ensure consistency.
During production, our in-process quality control (IPQC) personnel conduct regular inspections until the product line process is complete. This includes:
Regular Inspections: IPQC staff monitor production, and if any abnormalities are detected, supervisors are notified immediately to make necessary adjustments.
Post-Process Control: After production, additional techniques such as deburring, printing, PU coating, cutting, and gluing undergo standard inspection procedures.
After completing the production process, our quality control (QC) personnel conduct thorough inspections according to standard procedures. Key testing methods include:
Tension Test: This test measures the tensile strength of silicone products, ensuring they meet functional standards. Using a tensile testing machine, we assess whether the product achieves the required tensile range of 80.49N.
Elasticity Test: Primarily applied to silicone keys, this test evaluates the number of presses a key can withstand, typically between 300,000 to 500,000 times.
Temperature Resistance Test: We assess how silicone products perform under high and low temperatures, ensuring they do not crack or age prematurely. Testing typically ranges from -40°C to 280°C.
Size Test: To ensure proper assembly, we control size tolerances within ±0.3mm, accounting for the natural softness of silicone materials.
Hardness Test: We measure the hardness of silicone products, which typically ranges from 30 to 80. This is crucial for ensuring functionality and durability.
Appearance Test: A visual inspection assesses the quality and color of the product, ensuring there are no defects like bubbles, impurities, or discoloration.
Silicone products require various certifications for export, including:
FDA and LFGB: Certifying compliance for food contact materials, with FDA being the U.S. standard and LFGB the EU standard.
ROHS: An environmental report testing for heavy metals.
PAHs: Testing for polycyclic aromatic hydrocarbons, which are environmental pollutants.
REACH: Ensuring the safe use of chemicals in the EU.
MSDS: Providing safety data on materials.
Silicone products for U.S. FDA certification undergo several tests to ensure compliance with relevant standards:
Product Composition Analysis: Testing the main components and additives in silicone to confirm they meet FDA requirements.
Testing Items: Includes hazardous substance testing, safety evaluations, environmental safety assessments, and food contact material testing.
Relevant Standards: Compliance with U.S. FDA regulations such as 21 CFR 177.2600 and 21 CFR 175.105, which govern rubber and silicone products in contact with food.
