Cast Urethane Parts

Cast urethane parts are a specialty of DST. We can custom design and manufacture virtually any type of commercial or industrial cast urethane part to near net shape profiles. Cast urethane offers a longer service life compared to metal or plastic. The hardness of cast urethane parts varies from very soft to rock-like. Some types of cast urethane can be approved for FDA food contact applications. Cast urethane parts are generally lightweight, highly abrasion and impact resistant can vary in the coefficient of friction, and have excellent oil, ozone, and radiation resistance.

Cast urethane parts are often used in oil and gas exploration, printing, textiles, construction, agriculture, mining, packaging, automotive, material handling, food, and beverage as well as currency and ATM applications.

We offer you the option of low-cost, low-pressure tooling as well as limited productions runs. If you’re in a hurry, our rapid prototyping 3D printer is at your service to expedite your job. We can develop custom formulations to enhance the physical properties required by your application utilizing our decades of experience in polymer chemistry.

DST has a dedicated cast urethane work center designed specifically to enhance our automated cast urethane production equipment, utilizing the very latest lean manufacturing and Six Sigma techniques.  Call us today and put our cast urethane team to work for you!

Rubber Extrusions

We can extrude virtually any custom profile for your rubber extrusion application. We have worked on rubber extrusion projects for a wide variety of industries including poultry, furniture, door and window manufacturing (glazing), bottling, canning and bakery applications.

Our Engineered Polymers Division (EPD) operates a Davis Standard Cold Feed Thermoset Extruder. This state-of-the-art rubber extruder produces custom profiles for the food, beverage and airport baggage handling industries, just to name a few applications. It is highly accurate and maintains tight tolerances, producing superior extruded products, on-time and within specifications.

This extruder is capable of dramatically increased production runs. Thanks to this increased capacity, we now stock a wide variety of extruded rubber parts like rubber conveyor grippers, ready for same-day or next-day shipment. Of course, we are always ready to take on your custom rubber extrusion projects.  Call us today and let us quote your next project.

Rubber Rollers

Rubber rollers are a specialty of DST. When combined with our exclusive Millathane® millable polyurethane, our rubber rollers are, quite simply, the best in the industry.  Rubber rollers are often used in ATM machines and dispensers for transport and separator functions. Other common uses of rubber rollers include point-of-sale (POS) printers, printer rollers, receipt printers, printing press rollers, labeling rollers, newspaper/magazine printing rollers, and various paper path applications.

DST’s Millathane® millable polyurethane is known the World over for its superior ability to balance coefficient of friction and abrasion resistance in critical applications. In addition to Millathane®, we offer a wide range of elastomers for virtually any rubber roller application, such as EPDM, nitrile, neoprene, Hypalon®, epichlorohydrin and polyisoprene.

Materials

Acetals: Delrin® – Celcon®
Acetals are available as a homopolymer (Delrin by Du Pont) or a co-polymer (Celcon by Celanese). Both materials offer excellent machining properties and are ideal for holding close tolerances. The high compression strength and stiffness of acetal make it a good material for high-load applications. Acetal is also available with additives such as moly dry lubricants and Teflon® fibers. These reduce friction and aid machinability.

Nylons
Nylon is available in several compounds and co-polymers. The most commonly used nylons for industrial components are Type 6 (cast) and Type 6/6 (extruded). Both materials exhibit excellent wear resistance and tensile strength, with Type 6 offering slightly better mechanical properties. Nylon generally absorbs more moisture than other bearing materials and therefore may be dimensionally unstable in wet applications requiring close tolerances. Nylon is available in oil or molybdenum disulphide filled compounds which offer a lower coefficient of friction for bearings and wear parts.

PTFE: Teflon®
Polytetrafluoroethylene (PTFE) provides exceptional chemical, electrical, mechanical and thermal properties for many applications. The most recognized source of PTFE resin is Teflon manufactured by Du Pont. PTFE is capable of operating at temperatures up to 550ºF, making it a versatile high-temperature material. Glass fibers are often added to improve the dimensional stability of PTFE under load.

UHMW-PE: Duro-Glide®
UItra-high molecular weight polyethylene (UHMW-PE) has the highest impact and abrasion resistance of any thermoplastic. These properties and its reasonable cost make UHMW a versatile material for many applications where abrasion, impact, or chemical resistance is desired. The low coefficient of friction and high-slip properties of UHMW make it ideal as a wear liner for handling bulk commodities. UHMW can operate successfully at temperatures as low as – 375ºF, making it excellent for cryogenic applications.

Duro Lube
Oil-filled UHMW polyethylene is ideally suited for applications such as wear strips, slider plates and some bearing surfaces where lubrication is desirable to lower the coefficient of friction. All additives in Duro-Glide (white) and Duro-Lube meet FDA requirements for direct food contact.
