Following is the main information for your reference.

Pvc injection problem and the solution

1. Lack of material:The phenomenon that the mould can not be filled often occurs in the process of injection pipe fittings. When the injection molding machine just started to work, due to the mold temperature is too low, the heat loss of PVC molten material is large, easy to produce early solidification, the resistance of the mold cavity is large, and the material can not be filled with the mold cavity. This phenomenon is very normal, but also temporary, after continuous injection of digital model will automatically disappear. If the mold cannot be filled all the time, consider the following situations and make appropriate adjustments:

1: the temperature of the injection material is low and the fluidity is poor, so the heating temperature can be appropriately raised to improve the plasticization and fluidity of the material.

2: Set injection molding cycle is short, or insufficient material, can be appropriate to increase the injection time and increase the amount of sol.

3: If the set pressure is too low or the time of conversion from injection pressure to holding pressure is too early, the injection pressure can be appropriately increased or the time of conversion from holding pressure can be adjusted.

4: the injection speed is low, the injection speed can be appropriately increased.

5: the flow channel system structure size is small, can be appropriate to increase the volume of the main, shunt channel or the gate to be larger

6: mold exhaust is not good, can be appropriate to modify the gate position or open an exhaust groove.

7: thin wall filling mold is difficult, can adjust the structure of the product or change the gating system.

Procedure of UPVC reducing socket pipe fitting mould making
Step 1 place the order & receive the down payment
Step 2 Design and make the drawing( products& moulds)
Step 3 Customer check & confirm
Step 4 Steel material purchase
Step 5 Machine process(CNC, sparking machine, boring machine) & mould makers install
Step 6 Mould testing
Step 7 Send the samples to check

Packaging and transportation

1. Mould: after the mould is assembled and cleaned, apply antirust fog or antirust grease on the mould, then cover it with film and put it into a stable wooden box.

2. for plastic products: first use semi transparent thin foam plastics to wrap each part in plastic bags, and the second step is to put the thin sponge board into the carton to prevent scratches.

Design of mold cooling system

The design of cooling system is a complicated work, that is to design a good cooling effect and consider the uniformity of cooling, and also consider the influence of cooling system on the overall structure of the mold, the specific location and size of the cooling system are determined; Main consideration is cooling of moving die or insert; Cooling of side slide block and side core; Design of cooling elements and selection of cooling standard elements.
