Blow Molding Design


blow molding process

Our design process ensures that your product will have the proper structure, configuration and material for your application.

Working directly with our engineers, your final product will deliver the results you need. We consider multiple factors when designing your project to ensure high quality, reproducibility, and usability with your application. With nearly 40 years of experience designing custom blow molded products in a wide variety of materials and applications, we can meet all of your design needs.

STEP 1: Discuss Application, Specifications & Tolerances

To begin, our engineers will talk with you about what your project is and how your product needs to perform. We develop a full understanding of your needs and identify design factors such as:

  • Product’s specific application
  • What it will be exposed to
  • Potential weight loading
  • Environmental concerns
  • Structural requirements

For example, we frequently blow mold fuel pump components for gasoline dispensing. For that specific application, we provide a product that is static dissipative.


STEP 2: Select Your Materials

After we discuss your project’s requirements, together we will select the proper material for your application. We will ensure that you select the best material for your application, whether you need a commodity compound or engineered resin.


STEP 3: Design Project

Our engineers, factoring all of your discussed needs, will draft your product. We consider both internal and external design. Your design is custom to you. We design with manufacturability in mind to produce consistent, high quality products throughout our runs.


STEP 4: Build Your Mold

Once the design is finalized, we begin to build your custom mold.


STEP 5: Product SLA Models

We offer SLA models of your product before main production. We will ensure that your product is perfected before moving on to mass production.


STEP 6: Begin Production

After final approval, we begin to manufacture your product. Throughout production we inspect our molds and parts to ensure proper quality control. Each piece in your order will be made to specification.


STEP 7: Finishes

Any additional finishes and assembly will be done to specification before we ship your final product to you.
