Injection blow hollow forming machineHow to solve the unstable quality of blown products? Do you know? Today, let's learn about the related problems and solutions of injection blow hollow molding machine!
The quality of the blown products of the injection blow hollow molding machine is unstable:
The thin wall of the parison is uneven, and the thin wall of the blown product is uneven, which is easy to blow. If the die expansion pressure is too large, the die expansion pressure should be properly reduced; if the die expansion temperature is too high, the temperature of the mandrel and die should be adjusted and reduced; the air inlet position of the die expansion is unreasonable and should be corrected.
Injection blow hollow molding machine products matte or difficult to release:
The temperature of the forming die is uneven, and the temperature difference of each part is large, the heating temperature control system of the die should be adjusted or corrected; the working surface of the forming die has foreign matter or is not smooth, and should be cleaned or polished.
Injection blow hollow molding machine products at the bottom of the white:
When the mold temperature is low, the temperature of each part of the mold should be adjusted to be uniform; when the gate temperature is low, the gate temperature should be appropriately increased or the melt temperature should be increased.
bottle neck deformation:
In the case of short cooling time, melt inflation should be appropriately extended. The temperature of the neck of the forming die is too high, and the temperature of the die should be reduced appropriately. If the temperature of the steel core is too high, the temperature should be appropriately reduced; if the temperature of the cooling circulating water of the mold is too high, the water temperature should be appropriately reduced.

Today, the raw material belt equipment manufacturer tells you about the matters needing attention when the raw material belt is wound.
Raw material belt equipment: production process of raw material belt equipment
What is the production process of raw material belt equipment? Do you know? Today, let's learn about it together! The raw tape is produced and processed step by step by the raw tape equipment. Different raw material belt production process is not the same, oil and oil-free raw material belt production process is not the same.
Raw material belt equipment: application of raw material belt equipment
At present, the winding of the raw material belt is manual operation, and there are few special tools. If it is only a maintenance method, basically manual winding is enough, but if a large number of projects are installed. If a building needs to be equipped with a faucet, it is conceivable that the winding of raw material tape alone is a lot of work. Today, I 'd like to introduce you to the raw material belt equipment.
The travel switch of the injection blow hollow molding machine is an important part of the production process of the injection blow hollow molding machine. The detailed knowledge list of the travel switch of the injection blow hollow molding machine brought by the editor today will help you understand. What is the stroke switch of injection blow hollow molding machine? Simply put, it is to use the collision between the moving parts of the injection blow hollow molding machine to produce the contact action of turning on or off the circuit to achieve the purpose of control.
What are the precautions for the use of injection blow hollow molding machine? Do you know? Today, let's learn about it together! 1, can not be operated in the state of no material, can reduce the wear between the screw and the cylinder. 2. For the screw, it is recommended to use IKv screw plastic injection blow hollow molding machine. Under the same conditions, the yield is higher and the plasticizing energy is stronger. When the temperature of the cylinder and the temperature of the plastic material are not enough, do not operate to prevent damage to the screws and connectors.
