Blow Molding Part Design Expertise

We’ve designed several blow-molded products for different applications, including bottles. Some of the bottles were injection blow molded, and others were extrusion blow molded. We designed the threads to match custom injection molded caps or included features to engage with snap-on injection molded parts. Highly customized bottles were designed with two separate compartments containing chemicals that reacted after being mixed. Functional features such as these required complex mold design and close collaboration with the blow molder.

The blow molding manufacturing process efficiently produces low-cost hollow plastic parts. Although most blow molders specialize in bottle production, a smaller group of blow molders manufacture complex functional components such as automotive air ducts, toys, blow molded cases, and countless other unique products. No matter what type of blow molding applications you require, Integrated Design Systems (IDSYS) will help you create the exact product you need.

IDSYS is a world-class industrial design and product development firm with over 35 years of experience. We are recognized for our highly creative designs combined with exceptional plastics engineering expertise. This powerful combination of talents provides you with aesthetically appealing, cost-effective, and highly functional blow molded part design. Our small, highly specialized design and engineering team will work with you to ensure you get a high-quality product on time and on budget.

Blow molding can quickly produce any bottle or container with a hollow interior and is done via three method types: extrusion blow molding, injection blow molding, and injection stretch blow molding.

The extrusion blow molding process starts when a molten plastic material is formed through a parison, a tube-shaped piece of plastic with a hole to pass compressed air through it, and then clamped with a mold while plastic is pushed at the front to match with the mold. When the parison is the proper length, the two halves of the mold are clamped together around it. After it has cooled and solidified, the mold is opened up, and the part is removed.

If you are creating a product such as small medical or single-serve bottles, you may end up needing a blow molding design that uses injection blow molding. This method has three main parts. First, the plastic is injected into a mold, forming a plastic tube. The tube heated and blown into a cavity mold, forming a hollow part that is ejected. With injection stretch blow molding, the parison is heated, and air is blown into it to form the shape of a preformed mold. It can either be 4-stage or 3-stage process depending on the needs of the design: injection, reheat, stretch blow, and ejection. Three-stage uses the latent heat of the preform rather than a different reheating stage, saving on energy costs.

At IDSYS we will work with your company to create blow molding designs that work with whatever product you wish to manufacture. We have high standards for quality assurance and experience in designing numerous blow molded bottles for different applications, such as custom-designed bottles with two separate compartments containing chemicals that reacted when mixed. Bottles are designed with molded in threads matched with custom injection molded caps or features that engage with snap-on injection molded parts instead.

IDSYS has an extensive design portfolio where you can check out all the different industries we have worked with for blow molding design. We are certified internationally to create designs for medical devices, analytical instruments, and plastic products. We also help you with the ergonomics of your product through innovative blow molding designs that develop products that are always comfortable to use. Our teams can also help with the aesthetics and branding of the parts we create for you to ensure they are what you need for a high ROI.
