Pultrusion - Fiberglass Pultrusion

You may be asking yourself, what is plastic Pultrusion? And what benefits does plastic Pultrusion offer? First of all, Pultrusion is a manufacturing process, which uses fiberglass mats and rovings along with a liquid styrene resin to produce products, which have exceptional strength to weight properties. We manufacture products for markets including the window and door industry, tool handles, automotive, broom handles, lawn and garden equipment, building products and much more.

Secondly, there are many benefits to using pultruded fiberglass products. The Top 10 reasons or benefits of pultruded products over metal and wood include:

1. Exceptional strength to weight properties
2. Chemical and corrosion resistant
3. Excellent structural properties and dimensional stability
4. Independent of temperature extremes and humidity
5. Water and weather resistant
6. UV and fire retardancy
7. Low electrical and thermal conductivity
8. Very low coefficient of expansion
9. Consistent color throughout the part
10. Easily cut, chamfered and drilled

What is Pultrusion?

We also have expert engineering knowledge that we use to produce the complex profiles and resin systems that are necessary to solve our customer's problems. Teel's plastic Pultrusion also provide custom finishing operations including drilling, sanding, slotting, assembly and other machining operations. We have our own in-house machine design engineers who can build the equipment needed to reduce product costs and allow our customers products to get to market faster.

In summary, our Pultrusion Division has the engineering knowledge and manufacturing expertise in fiberglass products to achieve both low cost production and very high quality. For more information please contact, Pete Johnson at 608-355-4629 or pjohnson@teel.com.

Interested in pultrusion for your application?
Accurate and complete information is necessary for us to design and quote a custom part. Here is a list of information we will ask:

1. Explain how your part is used.
• What is its function?
• Is it used indoors or outdoors?
• What chemicals will it be exposed to?
• Temperature range – heat or
cold extremes?
• Special properties needed

2. Attach a print or drawing of the cross section.
• What are the critical dimensions
or functions?
• List the length(s) needed.
• Are there special needs, such as a
UV inhibitor or fire retardency?
• What tolerances do you require?
• What is the color? Does it need to
be an exact color match?

General Production and Tooling Information
Pultruded profiles can be run with a single stream or multiple streams. A customer’s annual volume and delivery requirements influence this decision, as does profile type. Complex and large profiles are likely to run on a single stream, while tubes and simple shapes may run on multiple streams. Tooling costs also vary with complexity and number of streams. The customer generally owns tooling for custom profiles. For unique profiles, there may be an additional investment to develop the process and build a unique guiding system. If volume can support multiple stream production, there is an economic trade off to consider when determining number of streams. The initial tooling cost is higher with multiple streams, but part price will be lower. Our engineers and customer support staff will assist you in determining how to best meet your needs.

What makes a profile pultrusion-friendly?
1. A wall thickness that is constant or varies within the profile by no more than 2.5:1. Wall thickness is determined by the requirements of the application. Minimum wall thickness for a pultruded profile is .070”, while the maximum wall can be .250" or more, if needed.
