What are your typical lead times?

There are many factors that impact part lead times including material availability, part volume, equipment availability, and packaging requirements. Typical lead time for an existing part is about 3 weeks.  Lead time for a new product is dependent upon complexity of the part and tooling required.  Feel free to contact our sales team for lead time information on your project.

Do you have a minimum run size?

Yes. We have a minimum order requirement of $500.  Please keep in mind that there may also be additional tooling costs for new products or special order materials which will increase the minimum order cost.

New Products

Can you help design the part?

While we do not have design engineers on staff, our experienced and knowledgeable sales staff is ready and able to assist you with your specific application. Our expertise in elastomers and rubber production processes enable us to help when you run into problems.

What is the process for getting a quotation?

Simply contact us at your convenience with your specific requirements via email, phone or fax, or use the convenient Request Quote button on our website.

Below is what is needed to get a quote: 

  • We can quote on your project utilizing your blueprint, CAD file, sketch, or sample part.
  • We also require estimated or actual volume requirements.
  • Any required specifications.
  • What environment the part will be used so we can assist you in the selection of the proper material.
  • Finally, be sure and give us your contact information so we can better respond to you.

How long does it typically take to get a quote?

If all of the information is provided up front, a quote can be generated in 24-48 hours. Mold quotes typically take longer due to the need to quote tooling.

What are your typical lead times for a new part?

Lead time for a new product is dependent upon complexity of the part and tooling required.  Feel free to contact our sales team for lead time information on your project.

Is the tooling required to produce the part made in- house?

We make all our extrusion dies in-house to maintain tight tolerances and ensure accurate profiles.  Molds are made by selected high quality local vendors.

Who owns the tooling after it is built?

The physical dies are the property of Northwest Rubber Extruders.  The customer purchases the rights to dies through a one-time non-recurring setup charge.  Once purchased, the dies cannot be used for another customer unless we receive prior written approval from the original owner.

The molds are property of the customer. We will maintain and store the mold while it is on our premises, however once contractual obligations are fulfilled, you are free to move the mold anywhere you like.

Are First-article Inspections Available?

Yes. First Article Inspections are performed on every new part prior to beginning production. After internal approval, the first-article inspection report along with the physical part will be shipped to the customer for approval. Once approved, we will move into the production phase and fulfill the order.  Please note that lead time for production begins after a first article is approved by the customer.

Can you perform AS9102 First Article Inspection?

Yes.  We can perform an AS9102 first-article inspection reports. The cost for this can vary depending upon the complexity and dimensions of the part, as well as the number of parts required for the report. Talk to your our sales team for more information.

Can you supply a PPAP report?

Yes.  A production part approval process (PPAP) is available to customers if required (level 1-5). The PPAP report requires additional cost and time to complete. Talk to our sales team for more information.

Can you supply SDS (MSDS) sheets?

No. SDS rules pertain to chemicals used in the workplace.  Federal regulation 29 CFR 1910.1200(b)(6), as set forth by the Occupational Safety and Health Administration (OSHA), states that an SDS (MSDS) is not required for an “article.”  An article is a “manufactured” item which:

1)    Is formed to a specific shape or design during manufacture;

2)    Has end use function(s)dependent in whole or part upon its shape or design during end use; and

3)    Does not release or otherwise result in exposure to hazardous chemical under normal conditions of use.

The typical products manufactured and sold by Northwest Rubber Extruders meet the above definition of an “article” and are therefore considered exempt from the SDS (MSDS) requirement.
