We take for granted the rubber on the bottom of our shoes — the material that grips and keeps us steady in tennis shoes, running shoes, casual shoes and even dress shoes. But how did the rubber sole of a shoe come to be so commonplace? And how do modern manufacturers mass produce the millions of rubber soles that need to be churned out each year in order to keep the world’s feet secure and comfortable?
We still use the same vulcanization method to create rubber for shoe sole material. Goodyear’s combination of curing, mixing and heating leads to the rugged shoe soles we know today.
We are a chemical specialty company that focuses on the mold release for polyurethane integral skin molding for shoe soles. We’re a small but important part of the process that helps shoes reach their completion and find their way onto your feet. The process includes:
This process can vary depending on the type of sole you’re creating and the type of shoe you’re creating it for. But the basic elements of the process are the same, and you can find this basic process in place at factories around the world. The rubber mixing and pressing operations are messy, with lots of moving parts and lots of excess, which is why the process is so often outsourced. But because these factories specialize in making rubber soles, they can do high-volume work and crank out an unbelievable number of soles each day — efficiently and accurately.
At W.N. Shaw, we specialize in polyurethane, rubber and composite molding, which includes release agents for both single- and dual-density unit soles. Since 1985, we’ve been serving manufacturers with custom model release agents, adding value through our cost-effective solutions and advanced technologies.
We can create custom mold release solutions for manufacturers operating in a range of industries, shoe production and beyond. We can also adapt as new technologies and innovations become available. We share your urgency in creating the most effective, most affordable processes possible.
We have hands-on experience gained on our own shop floor, where these custom release agents are tested and formulated. As we perfect these release agents, we make them available to manufacturers in the USA and Canada, and we make them available through distributors in Mexico, China, Japan, Asia, South American and Europe. Our global reach gives us real-time experience and knowledge into what’s working and what’s not, as well as the agents, products and capabilities that manufacturers most value.
We are proud to carry on the tradition of high-quality shoe sole production, honoring the legacy of Charles Goodyear. As a part of the shoe sole production process, we place an emphasis on attention to detail and delivering results that reflect the utmost in care. If you need custom mold release agents for the production of shoe soles, turn to W.N. Shaw — the company that offers the experience, knowledge and resources to get the job done.
