Blow molded products

Blow molding is a kind of molding process of placing the molten preform into the blow mold, injecting the compressed air, and the performance will be stick to the mold cavity wall, after cooling and mold release we got the blow molding products we want. Blow molding can be applied for the production of plastic containers as bottles, pots, barrels, and daily uses, children’s toys, etc.

The major materials for blow moldings are Polyethylene, PVC, polystyrene, linear resin, polycarbonate… The consumption of HDPE takes the first place in blow molding, it is widely used in food, chemical and disposing of liquid packaging. PVC container is more popular in cosmetics and detergent packaging for its good transparency and air-tightness.Blow molded products

With the development of non-toxic PVC and fertilizer and the scratch blow molding technology, PVC container for food packaging became widely used, like for beer or other carbon dioxide beverage packaging.

Others like PET blow molding containers are also widely applied production of food, drinks and commodity packaging containers.

Thanks to the advancement of resin modification and processing techniques, the consumption of PP has also been increasing year by year.

Compared with ordinary single-layer PE containers, multilayer compound containers PE/PA/PE is hard to see differences by their appearance, but they got big differences in performance, the multilayer container has its outstanding barrier property to oxygen, carbon dioxide, nitrogen, and organic solvent.

Our company is a professional plastic mold company and a reliable supplier of quality blow molded items & plastic mold parts, providing customers one-stop services from design, molds building, product production, printing and to final assembly. Plastic bottle user guide in the blow molding industry that we should know.

New Injection Blow Molding Machine Created – Inject2blow

Injection molding machinery maker Engel and Italian based molds making company CantoniSrl joint developed a process called inject2blow, with a combination of injection molding and blow molding in one mold on one injection molding machine. we call injection blow molding

The process will greatly help reduces the time and cost to producing cosmetic, pharmaceutical and food containers by this one-step molding method, and China will be a big market for this newly developed “injection blow molding” machine that will be a big challenge to that we are currently using “one-step vertical three-location”  blow molding machine.

Our company produces a great variety of high-quality HDPE injection blow molded tablet bottles and containers in 100K class cleanroom workshops, all of our bottle products are manufactured complying with GMP or FDA standards, and exported to European and American packaging and pharmaceutical companies.

Features of injection blow molding technique:

  1. One-step and fast molding without rough selvage, continuous production to meet the GMP standard; accurate dimensions on bottleneck and screw thread to meet various sealing requirements;
  2. The smooth half line between bottle body and bottom with exquisite appearance and changeable shape;
  3. Weight, wall thickness and volume can be designed and manufactured accurately;
  4. Multiple-cavity production for bottles of different volumes and high production capacity.
  5. Moldable for various thermoplastic raw materials such as PE, PP, PS, SAN, PETG, EVA, etc.;
  6. Various injection molding processes can be selected with large space and the molds easy to change

Major applications: pharmaceutical, food, chemical, and cosmetic bottle packaging industries.

When insert molding finished, we can get a hollow slot product by extra core hole processing.
