HCM is a supplier of Polyurethane and silicone Parts in Hamilton Ohio

Urethane, often used interchangeably with polyurethane, is a versatile polymer known for its exceptional durability, elasticity, and resistance, formed from a chemical reaction between isocyanates and polyols to create a strong urethane linkage. It's used in countless forms—foams (insulation, bedding), coatings (protective layers), adhesives, and solid parts (wheels, seals)—offering high load-bearing capacity, abrasion resistance, and resilience, outperforming rubber and plastics in many industrial and consumer applications

Urethane vs. Polyurethane

• The term "urethane" refers to the chemical linkage (R-O-CO-NH-R).
• "Polyurethane" means many urethane linkages, referring to the resulting polymer material.
• Essentially, the urethane part is a polyurethane part, but polyurethane describes the polymer with multiple linkages. 

Durometer is a standardized measurement for the hardness of materials like rubber and plastics, indicating their resistance to surface indentation. Higher durometer numbers mean a harder material, while lower numbers indicate a softer, more flexible material. Common durometer scales, such as Shore A and Shore D, range from 0 to 100, with the specific scale used depending on the material's hardness. 

Common scales 

• Shore A: This is the most common scale and is used for softer materials like rubber, non-rigid plastics, and elastomers. Examples include rubber tires (70A) and rubber bands (25𝐴).
• Shore D: This scale is used for harder materials like hard plastics, hard rubber, and semi-rigid plastics.
• Shore 00: This scale is used for very soft materials, such as gels and soft rubbers, which are too soft to be measured on the Shore A scale. 

Our Service and Engineering will guide you through the process of choosing what types of materials and which durometer you need. This decision can vary due to hundreds of different applications that are used in manufacturing

We focus on Custom molded parts that meet many special applications. We would start with design consult and then work in the quoting process after determining what the customer needs. We can supply any quantity for the application.

Yes! HCM has its own in-house machine shop with the most up-to-date machining capabilities. Customer would purchase the Mold/Tooling and HCM will store the tool at Their Facility with zero storage fee. The Customer Owns the mold/Tooling. There are options for burying the cost in the Per part price.

Every application is different. We would first discuss the specific application. There are several Factors

1. Does this need to be FDA/Medical approved Material
2. Is the part exposed to any oils or solvents
3. What forces and pressures are being applied to the Part
4. What is the daily. Weekly/monthly…. Usage of the Part
5. What is the Part expected to do…Seal, Guide, Push or Pull, Drive or roll. ETC

Yes, however, we will consult to give the best options for price and delivery. Sometimes, simplifying the design of the part can save thousands of dollars.
