It’s well understood that quality control is a crucial factor for all manufacturing and engineering practices throughout industry. Without quality control, all aspects of product planning and launch can result in failure. What follows are some of the key issues that must be considered for quality control in a blow molding project.
Blow molding refers to the manufacturing process that’s used to produce plastic containers and similar products. This generally includes hollow containers such as pop, juice, and water bottles, as well as liquid soap and shampoo bottles. But the full range of blow molded products is remarkably diverse – everything from vitamin and medicine containers to special custom-designed forms can be made using blow molding – and the method is used throughout industry on an international scale.
Given the scope of blow molding, any company that’s planning to create containers for their products needs to be fully focused on quality. What follows are the basic critical factors that must be considered. These points should be discussed with plastics engineers when considering the most suitable manufacturing methods:

The four main blow molding quality control factors that need to be addressed for quality assurance are:

  1. A careful determination of product requirements in the planning phase;
  2. An adherence to all product specifications during manufacturing;
  3. An assurance of the manufacturing production standards;
  4. A quality assurance program to ensure product quality after manufacturing and before going to market.
