What is the processing technology flow of liquid silicone wrapped metal material products?
The processing technology of liquid silicone coated metal products is a complex process involving multiple steps and technical details. Here is a detailed process flow to help you understand how to produce liquid silicone coated metal products:
1. Design and Planning
Product Design: Design the structure and dimensions of liquid silicone coated metal products based on customer needs and product functionality.
Mold design: Design molds suitable for liquid silicone coated metal products to ensure that the molds can accurately wrap metal parts.
2. Material preparation
Metal component preparation: Select suitable metal materials such as aluminum alloy, stainless steel, etc., and perform surface treatment such as grinding, sandblasting, chemical treatment, etc. to increase the adhesion between silicone and metal.
Preparation of silicone material: Select suitable liquid silicone material to ensure its flowability, hardness, and curing characteristics meet product requirements.
3. Pre treatment of metal components
Cleaning: Use appropriate cleaning agents to clean metal parts and remove surface oil stains and impurities.
Surface treatment: Grinding or sandblasting the metal surface to increase the bonding area between silicone and metal.
Bottom coating treatment: Apply a layer of bottom coating agent, such as silane coupling agent, on the metal surface to improve the bonding strength between silicone and metal.
4. Mold preparation
Mold cleaning: Clean the mold to ensure that there are no impurities or residues inside the mold.
Mold preheating: Preheat the mold to an appropriate temperature according to the curing requirements of the silicone material.
5. Injection molding
Metal component positioning: Place the pre processed metal components in the predetermined position of the mold to ensure accurate positioning of the metal components.
Silicone injection: Inject liquid silicone material into the mold through an injection machine to ensure that the silicone can evenly cover the metal parts.
Curing: According to the curing requirements of silicone material, control the curing temperature and time to ensure complete curing of silicone material.
6. Demoulding and post-processing
Demolding: After the silicone material is completely cured, carefully remove the product from the mold to avoid damaging the product.
Post processing: Necessary post-processing of the product, such as removing burrs, cleaning, inspection, etc., to ensure product quality.
7. Quality inspection
Dimensional inspection: Use high-precision measuring tools such as micrometers or coordinate measuring instruments to check whether the dimensions of the product meet the design requirements.
Appearance inspection: Check the appearance of the product to ensure that there are no defects such as bubbles, cracks, deformation, etc.
Functional testing: Conduct necessary functional tests based on the product’s functional requirements, such as waterproof testing, pressure resistance testing, etc.
8. Packaging and Storage
Packaging: Use appropriate packaging materials, such as anti-static bags, foam, etc., to package the product to prevent damage during transportation.
Storage: Store the product in a dry, ventilated environment, avoiding direct sunlight and high temperatures.
9. Delivery and Feedback
Delivery: Deliver the product to the customer, ensuring that the product is in perfect condition.
Feedback: Collect customer feedback and improve production processes and product quality in a timely manner.
summary
The processing technology of liquid silicone coated metal products includes multiple steps such as design and planning, material preparation, metal component pretreatment, mold preparation, injection molding, demolding and post-treatment, quality inspection, packaging and storage, delivery and feedback. By strictly controlling the quality and process parameters of each step, high-quality liquid silicone coated metal products can be produced.
