Urethane Slide Bumpers – High / Low Rebound Bumpers

Urethane Slide Bumpers can be custom formulated to suit your exact needs. Plan Tech specializes in manufacturing both high rebound urethane slide bumpers and low rebound urethane slide bumpers. Custom cast urethane slide bumpers will re-direct product to continue on track down an assembly line or direct products for packaging.


Urethane slide bumpers will also help stop the harsh slamming of products without the bouncing back rebound while protecting the product from damage with reduced noise vs. similar materials. At Plan Tech we can reverse engineer existing slide bumpers to match OEM specs. Adding a core for bolt applications is also no problem for us! Often times we can add additives that will increase abrasion resistance and add lubricity to keep products from sticking. An Anti-static additive is also common to reduce any static build up from sliding friction.

Molding Urethane Parts Open cast

Open cast molding is the simplest and most common molding method for thermoset polyurethanes. Advantages: Since pressures and temperatures in the molding process are relatively low (ambient pressure and temps below 250F), the molds are more cost effective and can be made from a variety of materials including polyurethane. Open cast molding urethane parts is good for parts with relatively open tolerances on one surface. If tolerances are tighter, a secondary finishing operation is an option.


Molding Urethane Parts Transfer and Liquid Injection

In transfer or liquid injection, pressure is used to force the liquid polyurethane out of a reservoir and into the mold. Materials are generally injected at the bottom of the part and vented at the top for the prevention of air entrapment. Advantages: Makes use of fairly low-cost molds and can achieve thin cross-sections. Parts will have a sprue and an open surface for venting air which will require a finishing operation.
