1. What products in life are blow molded by special process?
A: Decorative balls are made using the extrusion blow molding process, not injection molding. Car jack boxes are not blow molded rather than injection molded. Compared with injection molding process, the advantage of extrusion blow molding process is that it can reduce the use of raw materials and save costs in mass production when the product does not require high physical properties.
2. How to solve the problem of edge clamping?
Answer: First of all, the clamping edge of the product is judged to determine which direction the locking mold frame needs to move (the clamping edge is on the side of the product, the locking mold frame will move to the side), and then loosen a FIXED M8 and four M6 screws on the swing frame cylinder, and then move the swing frame by twisting the swing frame cylinder with a wrench in the direction just judged. After moving, tighten the screw that has just been loosened, and align the inserting pen.
3. What kind of bottle blowing machine does it have? What are the advantages and disadvantages of different types of bottle blowing machines?
A: The type is divided into hybrid, all-electric, speed dragon models. The advantages of oil-electric hybrid are that the swing frame and plug pen are driven by electric servo motor, which will not leak oil and is more energy saving and environmental protection. Disadvantages: because the clamping is hydraulic, there will be the risk of oil leakage. The advantage of all-electric is that the swing frame action, insert pen, locking adopts electric servo drive, no oil leakage, more energy saving and environmental protection. Disadvantages: clamping force will be smaller than the hydraulic press. The advantage of velong machine is that the output is increased by 20%-40% than the original, the locking frame swing frame is equipped with electronic brake, the action is more stable and faster, the pen insertion system is equipped with bottle rapid cooling system + bottle rapid cooling pen insertion device, so that the cooling speed of products is faster.
4. What are the advantages of our bottle blowing machine?
Answer: high cost performance, moderate price, after-sales service coverage points, high retention rate, strong durability of the machine.
5. What kind of bottle is suitable for bottle blowing machine?
A: Such as washing products, hotel supplies, personal goods, food, medicine, pesticides, wide mouth bottles and other PETG and PVC packaging industry, can use Leshan blowing machine to produce.
6. How does rapid cooling in bottle increase production?
Answer: The hot gas in the bottle after molding in the mold can be discharged rapidly through the air circulation pen and air circulation function, which can improve the cooling speed and increase the output.
7. In a double-layer machine, can raw materials be put together at the same time to produce products? Such as outer PP, inner PE raw materials.
Answer: No, because the material properties are different, the heating temperature of the two materials is also different.
8. Besides bottle blowing machines, what other services and products can we provide?
A: Also provide close mold, auxiliary system, key engineering services.
9. Why does the customer choose a three-layer machine to produce 5L oil drum?
A: An outer layer, an inner layer, and a liquid level line. The inner layer can use 30% new material and 70% nozzle material to realize cost saving.
10. How to effectively solve the vibration problem of bottle blowing machine at work?
Answer: Adjust the pressure and flow parameters of PQ valve of swing frame to make the movement of machine swing frame more stable.
