How to choose the right hollow blow molding machine for you

Nowadays, there are many manufacturers of hollow blow molding machines, which are all kinds and mixed. How to choose a suitable hollow blow molding machine without spending money is very important. There are actually many pitfalls in the promotion of hollow blow molding machines. Some people buy hollow blow molding machines thinking that they have found cheap ones, but this is not the case, and there will be many troubles in the future.

Before choosing a hollow blow molding machine, you must first analyze your own products and the products you need to do in the future to choose a product that suits you. Such as analyzing the weight, size and requirements of the product, as well as what material it is. The size of the weight determines the size of the equipment and whether it is made with a multi-die head or a dual-station multi-die head. If the product has more than four or five hundred grams, it may be necessary to choose a fixed mold opening and closing equipment of 75 or more. For small machines, the size of the mold opening and closing, the stability of the mold transfer, and the stability of the blowing needle position should be considered. If these will change frequently, it will affect the quality and efficiency of the product. Some customers bought the equipment back at a very cheap price, and it turned out to be a decoration. The reason is that it is very unstable, requiring people to watch and adjust constantly, which is time-consuming and labor-intensive. The small machine depends on the configuration and material, as well as the rationality of the design. Generally, the small machine is relatively standard, and the optional accessories are relatively small.

There are many options for large machines above 75, such as blowing, manipulator, wall thickness controller, etc. Configurations are also good and bad. Some people with the same model have a small motor, and the product in front of them can be made. Once there is a slightly larger product, it is not easy to make. Some manufacturers of equipment such as 120 are relatively cheap, but the motor is only 90KW. Of course, it can be done, but it will affect the plastic power. What you can't see is the clamping force, which is also a 90 machine, and some clamping forces are too small. At present, there are domestic wall thickness controllers, B&R's, and Japanese MOOG's, and some of them are made in PLC at very low cost. The best thing to use is the Japanese MOOG wall thickness controller, which is relatively expensive.

Energy saving is also very important, and the level of electricity bills directly affects the cost of products. At present, there is no good energy-saving method for small machines. Large machines have more energy-saving. The twisted material is variable frequency twisted material. We mainly consider the oil pump. At present, there are three forms: 1. Energy saving by accumulator; 2. Energy saving by frequency conversion; 3. Energy saving by servo; If you choose domestic servo, it will be cheaper, if you use imported servo, the cost will be higher.

In short, the choice of equipment must be solid. I wish you to choose your favorite product.
