(1) PP polypropylene cannot be used: refurbished materials and hammer materials produced in the production of products. If these materials are used, it will seriously affect the toughness and softness of the product, and it will easily lead to aging and fracture of the product and affect the quality of the product.
(2) Ink should choose proprietary PP polypropylene ink, so the adhesion to the product is greatly increased, and it is not easy to fade.
(3) The stainless steel card of the spring should be selected from stainless steel. The rust-proof and stainless steel card should have good hardness and elasticity. It should not be too thin or too thin, which will cause the seal to fall off during use.
(4) Glue should be selected from PP plastic glue and assembly process.
Plastic seals are generally polymer compounds synthesized from plastics, also known as polymers, which are also commonly known as plastics or resins, which can change the shape of the body. There are many types of construction materials commonly used in plastic seal products. The commonly used plastic seals are made of a thermoplastic engineering plastic.
The material used for plastic seals is polyethylene: commonly used polyethylene can be divided into low-pressure polyethylene, high-pressure polyethylene, and linear high-pressure polyethylene. Among the three, HDPE has better thermal, electrical, and mechanical properties, while IDPE and LLDPE have better flexibility, impact properties, and film-forming properties. IDPE and LLDPE are mainly used for packaging films, agricultural films, and plastic modification.
The plastic seal is made of PVC. It is a thermoplastic resin polymerized by vinyl chloride under the action of an initiator. It is a homopolymer of vinyl chloride. Vinyl chloride homopolymers and vinyl chloride copolymers are collectively referred to as vinyl chloride resins. It has good elasticity and impact resistance, so it is often used as a raw material for plastic seals.
Introduction to the role and manufacturing process of plastic seals: The seals are made of PP plastic in a single injection molding. The steel sheets are sandwiched within the seals. The product is at minus 45 degrees and minus 50 degrees. The locking lever is a 2 * 5 flat lever, which can be adjusted and tightened at will when sealing. The color can be made into red, blue, green, and yellow, and other colors can also be made according to user requirements.
Plastic seals are accessories made of plastic that are used to fix wires, cables, and other circuits. The plastic seal is assembled by two parts. One end is a square plastic mouth with a hook-shaped elastic plastic buckle. The other end is a plastic seal body with a serration. The body can be bent through the plastic mouth in front. In this way, the ring shape is formed, and the cable can be used as a belt for pants. Because the serrations on the seal can be linked with the elastic plastic in the plastic mouth, the plastic seal can play a fixing role.
