Some examples of consumer products made possible with a top-of-the-line stretch blow molding machine include water bottles, milk jugs, peanut butter jars, shampoo and cream rinse bottles, storage tanks, and plastic drums. Not only can this equipment produce a broad range of shapes but also items from small to large. This shows that the stretch blow molding process is widely used by many different industries.
The other great thing about a PET stretch blow molding machine is that customers can use many different materials. The selection depends on the product. For instance, drums need a thicker wall to give them stability, while soda bottles require thinner walls. Regardless there are two crucial factors to ensure that businesses manufacture what they need to their specifications.
The first involves buying a stretch blow molding machine from a trusted source. That gives customers the assurance they need to feel confident in their investment. As expected, a reputable company is going to sell only the best equipment while keeping prices competitive. The second key to success comes from choosing the appropriate material. After all, they all have different qualities and characteristics.
Keep in mind that along with the product, the type of material depends on the plastic resin properties, the cost of the material, the processing properties, and the objectives for the finished part or component. There are thousands of plastics available. However, the majority won’t meet the needs of the manufactured product.
Least Expensive Plastics
For companies that need to keep the cost down, any of the following materials would be ideal for the stretch blow molding process.
- Polyethylene (PE)
- Polypropylene (PP)
Of the two, PE is at this time, the least expensive. However, for companies that need a stiffer plastic material, PP makes the better choice. Both of these options have excellent resistance to most chemicals. For temperature performance, the choice all depends on the temperature range used. For instance, PE performs best for temperatures ranging from minus 75 to plus 180 degrees Fahrenheit. In comparison, PP is suitable for temperatures from zero to plus 170 degrees Fahrenheit.
For the stretch blow molding process, customers can also select from different engineering resins. These include:
- Acrylonitrile-Butadiene-Styrene (ABS)
- Polypropylene Oxide (PPO)
- Polycarbonate (PC)
- Glycol Modified Polyester Terephthalate (PETG)
- Thermoplastic Elastomer (TPE)
For customers interested in buying equipment they can count on, they’ll never go wrong choosing a PET stretch blow molding machine.
