Design to Completion Process

With over 40 years of experience designing custom blow molded products in a wide variety of materials and applications, we can meet all your custom design needs.

STEP 1: Discuss Project Requirements

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:

  • Part Dimension and Tolerances
  • Required Material
  • Strength Requirements
  • Environmental Considerations

After reviewing the deliverables of your project, we will offer suggestions on how to improve the manufacturability of the part.

STEP 2: Design Part

Our engineers, factoring all your discussed needs, will draft your product. We consider both internal and external design of the part. Your design is custom, and your input will be welcome throughout the design and revision process. If desired, 3D printed rapid prototyping is a service that we are happy to provide to you for a small charge. We find that this is very helpful to visualize the part and helps our customers give valuable feedback pre-production.

STEP 3: Quote Production Cost

Once the drawing is approved, we will work up a production quote for you to review. Once the quote is approved and you have placed a PO for the tooling and first samples, we will proceed according to the lead time provided in the quote.

STEP 4: First Product Samples

We will fully measure the initial samples to ensure that the part is within the drawing tolerances. We will then send you the samples for approval. At this stage we can add engraving or leveling on the part.

STEP 5: Sample Approval and Full Production

Once the samples are fully approved, we are ready to begin producing your product at the highest quality available.
