In the two-stage process, the preforms are moulded in a dedicated injection moulding system which produces fully-cooled preforms. These preforms can then be stored, shipped, and even sold, before being blow moulded in a different machine. The blow molding machine unscrambles the preforms, reheats them with infrared radiation, and conditions them before blow molding.

(ISBM) Injection Stretch Blow Mould Two Stage is a unique manufacturing process that is mostly related to the creation of hollow and light thin-walled manufacturing products which include bottles and jars made from plastics. The two-stage ISBM process is widely used in manufacturing PET bottles for soft and alcoholic beverages, cosmetics, pharmaceuticals, etc. , as it provides high-quality durable bottles.
Two-Stage Process:
Stage 1 - Injection Moulding: In the first step it involves melting of the plastic resin and then injecting it into a preform mould which forms the shape of a test tube that is referred to as the preform. This preform is in the form of the final product only that it is comparatively much smaller in size and thicker in dimension.
Stage 2 - Stretch Blow Moulding: The preform is then put back into a high temperature and when molten it is placed in a blow mould where it is stretched and blown to the final shape of the container. This process helps avoid variations of the wall thickness and guarantees high visibility in the final switch.
High Production Efficiency: The technique of using two stages of work also makes it very easy to mass produce with high levels of standardization.
Superior Container Quality: The application of this method results in containers with superior mechanical characteristics, clarity and surface finish. The stretching process enhances the order and the inter chain distance which enhances the strength and durability of the product.
Design Flexibility: Due to the two-stage process of the ISBM the blouse can be manufactured in different shapes of containers and a variety of sizes, intricate neck finish.
Cost-Effective: It is interesting to note that this step enables efficient control when it comes to blow moulding or injection since the two items are separated hence enhancing efficiency when it comes to the use of material and energy.
Additionally, companies can benefit from Extrusion Blow Moulding (EBM), which excels at producing larger and more complex hollow items with varied wall thicknesses. EBM allows for greater production speed and cost efficiency, particularly for specific applications.
Beverage Industry: They are used extensively in the production of PET bottles for water, soda, juices and all kinds and forms of beverages.
Pharmaceuticals: Perfect for fashioning utterly clean and high quality bottles for liquid forms of medications.
Cosmetics: Employed in the making of graceful containers for perfumes, lotions, and many related products considered beauty products.
Household Products: Ideal for the production of crates for detergents, cosmetics and the likes.
