Precision IBM Injection Blow Molding Machine One-Step Process Integration for Small and Medium-Sized Hollow Products

A. Process integration, one-step molding
The injection blow molding machine integrates the two processes of traditional injection molding (making parisons) and blow molding (forming into hollow products) on the same equipment, and realizes process switching through the rotation or movement of the mold. There is no need to manually transfer the parison, which reduces the intermediate links.
Advantages: Avoid dimensional deviation caused by temperature changes during the transfer of the parison, improve product accuracy (such as the concentricity of the bottle mouth thread); at the same time, reduce manual intervention and reduce production losses.
Applicable scenarios: Especially suitable for the production of small and medium-sized, structurally symmetrical hollow products (such as medicinal bottles, cosmetic bottles, food packaging bottles, etc.).

B. High product precision and stable quality
Good dimensional consistency: The wall thickness and shape of the parison are controlled by precision molds in the injection molding stage, and the parison is evenly fitted to the inner wall of the mold with the help of high-pressure air in the blow molding stage to ensure that the dimensional tolerance of the product is small (such as the bottle mouth diameter error can be controlled within ±0.05mm).
Excellent surface quality: The finish of the mold cavity is directly reflected on the surface of the product. With precise temperature control, high-finish products without scratches and bubbles can be produced to meet high-end packaging needs.
Reliable mechanical properties: the preform is fully plasticized during injection molding, the molecular chain is arranged more evenly, and the impact resistance and corrosion resistance of the blow-molded product are better than those of traditional blow molding processes (such as extrusion blow molding).

C. High production efficiency and strong automation
Continuous production: Injection blow molding machines usually adopt a multi-station turntable structure (such as 3 stations and 4 stations) to complete injection molding, blow molding, and product demolding respectively. Each process is carried out simultaneously, and the hourly output of a single device can reach hundreds to thousands of pieces (depending on the size of the product).
High automation integration: It can be equipped with automatic feeding, waste recycling, online detection (such as wall thickness detection, leakage test) and other systems to achieve unmanned production throughout the process, reduce labor costs and improve stability.

D. Wide material adaptability and saving raw materials
Applicable materials: It can process a variety of thermoplastics such as polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), polyvinyl chloride (PVC), etc. Some models also support the molding of engineering plastics (such as PC, ABS).
High raw material utilization rate: The wall thickness of the injection molded parison can be precisely designed through the mold to reduce the amount of excess material; compared with the "flash" waste of extrusion blow molding, the waste of injection blow products is less, and the raw material loss rate can be controlled within 5%.

E. High equipment investment, suitable for mass production
Injection blow molding machines integrate two systems, injection molding and blow molding, and have high requirements for mold precision. The initial equipment and mold investment is large, and it is more suitable for large-scale, standardized product production (such as medical packaging, beverage bottles, etc.). For small batches and multi-specification products, its flexibility is slightly lower than that of extrusion blow molding machines.
