How to choose the right hollow blow molding machine

Nowadays, there are many manufacturers of blow molding machines in China, and there are many different kinds of blow molding machines. How to choose the right hollow blow molding machine and do not spend money in vain especially off important. Promote the actual hollow blow molding machine many traps, some of the purchase of hollow blow molding machine thought to pick up a bargain, but not, after the trouble a lot of things.

Before choosing a blow molding machine, we must first analyze our own products, and the products we need to do in the future, to choose a product that suits your needs. Such as analysis of the weight of the product, size and requirements, and what material. The size of the weight determines the size of the equipment, as well as whether it is done with multiple die heads, or with a duplex multi-die head. If the product has more than a few 400 or 500 grams, you may have to choose more than 75 fixed open and close the mold equipment to do. For small machines to consider the size of the open and close the mold, the stability of the mold shift, the stability of the position of the blowing needle, if these will often change, it will affect the quality and efficiency of the product. Some customers spend very cheap money to buy back the equipment, the results when the ornaments. The reason is that it is very unstable, the need for people to keep watching, constantly adjust, time-consuming and laborious.

Small machine depends on the configuration and material, and the rationality of the design. General small machine is more standard, optional accessories are relatively small.   More than 75 large machine optional more, such as the following blow, robot, wall thickness controller, etc.. There are good and bad configurations. The same model has a small motor with a small, immediate product can do, once there is a slightly larger product is not good to do. Such as 120 equipment some manufacturers are cheaper, but the motor is only 90KW, of course, can do, but will affect the amount of plastic force. Can not see the clamping force, the same 90 machine, some clamping force is small. Wall thickness controller currently has a domestic, Bergamot, and Japan MOOG, some are done in the PLC inside the cost is very low. z good to use is the Japanese MOOG wall thickness controller, relatively speaking, the price will be slightly higher.

Today's era of energy saving is also very important, the high cost of electricity directly affects the cost of the product. Small machines are not yet any good way to save energy, large machines are more energy efficient, stranded material is frequency stranded material, we mainly consider the oil pump piece. At present there are three forms: 1, accumulator energy saving; 2, frequency energy saving; 3, servo energy saving; Z good effect is of course servo energy saving, relatively speaking the cost will also be a little higher. If you choose a domestic servo will be cheaper, such as the use of imported costs will be higher.

In short, the choice of equipment must be realistic. Wish you choose to your favorite products.
