1 Classification of PVC fittings?
A: PVC can be divided into soft PVC and hard PVC. Hard PVC accounts for about 2/3 of the market, and soft PVC accounts for 1/3. Soft PVC is generally used on the surface of floors, ceilings, and leather, but since soft PVC contains plasticizers (this is also the difference between soft PVC and hard PVC) and physical properties are poor, its use range is limited. Hard PVC does not contain plasticizers, so it is easy to mold and has good physical properties, so it has great development and application value. In the production process of PVC materials, it is bound to add several kinds of additives, such as stabilizers, plasticizers, etc. If all of them use environmental protection additives, PVC pipes are also non-toxic and tasteless and environmentally friendly products.
2 How long does it take to produce PVC pipe fittings?
A: For general PVC pipe fittings, we have a minimum order quantity. The minimum set-up quantity is generally 10-20 days, but it is similar to a 90-degree elbow/three-way tee/reducing tee/pipe plug, etc. If there is Inventory, generally 2-3 days, if not, 10 days can be completed
3 What is the production process of PVC pipe fittings?
A: Raw material + additive preparation → mixing → feeding and feeding → forced feeding → conical twin screw extruder → extrusion die → sizing sleeve → spray vacuum shaping box → soaking cooling water tank → ink printing machine → crawler traction Machine→lift knife cutting machine→pipe stacking rack→finished product inspection and packaging.
