Blow molding and rotomolding are two commonly used hollow plastic forming processes. Yankang Plastic Machinery has been focusing on blow molding for 20 years. Compared with rotomolding, where is it better to blow molding?   What is Blow Molding? Blow molding is out from the extruder, is still in a state of softening tube thermal plastic blank into the forming die, and then into the compressed air, use air pressure to make along with the cavity deformation, blow to make…

Are you still using a traditional resistance heater? Do you know the induction heater? Why not choose it? Maybe you really need to know more about the induction heater. The heater is an important part of the blow molding machine. The purpose of heating is to melt the plastic and form the material embryo. The plasticizing rate of plastics can be increased by proper temperature. In the pursuit of high efficiency and energy saving in today’s society, many blow molding…

In the plastics industry, everyone will hear the term of blow molding. What is blow molding? Do you really know? Today, Yankang will take you to know more about it. What is blow molding? Blow molding is a method of forming hollow products by means of gas pressure to blow and swell hot melt embryos closed in the mould. The hollow blow molding is to extrude from the extruder and put the tubular thermoplastic blank which is still in the…

Today, Yankang will share a detailed introduction about multilayer co-extrusion blow molding.   Firstly is “WHAT”   What is multilayer co-extrusion blow molding?   Multilayer co-extrusion blow molding is the technology of making hollow container by blowing molding. It uses more than two extruders to melt and plasticize the same or different plastics in different extruders. And then compounding, extruding and forming multi-layer concentric composite parison in the die. Its basic process principle is the same as the single-layer blow moulding…

Blow-molded pallets and inject molded pallets are two common methods for plastic pallet production. Now, plastic pallets have been widely used in many industries and provided great convenience. Which one is better? As can be seen from the title of the article, what we recommend is blow-molded pallets. Why choose blow-molded pallets? The following content will give you Strong Reason.   Let’s first understand the molding process of it. In general, its molding process adopts a large blow molding machine.…

The inverter energy savings? Is that true? The answer is YES!   In the following content, we have sorted out some of the customer’s questions about inverter energy savings. Expect the practical energy savings effect by the different working situations. Question 1: If two identical motors work at 50HZ power frequency, one uses an inverter, the other does not. Rotational speed and torque are in a rated state of the motor. So, can the inverter save electricity? How much energy…

Today, we’ll share the seven major points of blow molding moulds maintenance. During the use of blow molding moulds, it’s unavoidable to emerge some faults. Blow molding moulds maintenance needs professionally trained engineers. Familiar with the technical standard of blow molding moulds maintenance. Let’s get straight to the point. The sliding part should be thoroughly cleaned up and inspect and maintenance care. Such as core-pulling mechanism and guiding device. Re-lubricate with high-temperature grease and assemble. If there is a hydraulic…

Before blowing molding with a new mold or blow molding machine changes other molds for production, mold testing is a necessary step. The quality of the mold testing results will directly affect the follow-up production effect. Therefore, it is necessary to follow reasonable operation steps and record useful technical parameters during the process of mold testing of the blow molding machine. In order to facilitate the normal use of the blow molding machine and smooth production of blow molding products.…
