In recent years, China’s blow molding machine industry has developed rapidly, but it is far from being able to adapt to the needs of national economic development. The main problem is the excess of low-end blow molding machines, but the high-end blow molding machines are in short supply and must even rely on imports. Therefore, the blow molding machine enterprises must identify their own weaknesses. The gap between us and our foreign counterparts is mainly in the following five aspects.
Raw material problem
Due to the price restriction, domestic bottle blowing machines mostly use 2Cr13 and 3Cr13 for precision heat treatment, while foreign countries use special blowing machine materials DINI, 2316, their comprehensive mechanical properties, wear resistance, corrosion resistance and polishing brightness are significantly better than domestic material. This fundamentally affects the appearance quality and service life of domestic blow molding machines.
Manufacturing process level
Domestic blow molding machine manufacturers, the process conditions are uneven, the gap is very large. Many manufacturers rely on manual work to complete a lot of work, which seriously affects the accuracy and quality.
Blowing machine design system
Although some domestic manufacturers have adopted computer-aided design (CAD) and computer-aided manufacturing technology (CAM), they still stay in the stage of introduction, digestion and absorption, and it is difficult to form a mature theoretical guidance and design system. Therefore, it is imperative to standardize the development of the blowing machine design software system.
The blow molding machine is, in its essence, a tooling, and the production of a qualified product is the ultimate goal. Therefore, the quality and performance of the blow molding machine depend on the test results. Due to the short delivery time and limited test equipment, the domestic blow molding machine often puts the quality inspection work on the user’s test mode, which is easy to cause a lot of loss and waste to the user. Moreover, it is often difficult to debug the best state due to time and site restrictions. Some well-developed foreign companies have their own test sites and equipment, which can simulate the working conditions of users, so they can achieve good results in the shortest time limit.
China’s blow molding machine manufacturers are accustomed to burying themselves in production research, while neglecting cooperation with other equipment suppliers and raw material suppliers. Invisibly, the user has taken many detours. Our blow molding machine factory must cooperate with other manufacturers and major research institutes to create the best products for users and create greater profits, so that we can hope to create a broad space for development.
