Ames has been manufacturing precision custom-molded products for over 60 years. By combining various molding capabilities, materials development and finishing technologies, our products meet the most demanding applications and product tolerances.

Custom Molded Elastomers

We obtain optimum performance from a broad range of materials from natural rubber to synthetic elastomers. These includes NR, BR, SBR, NBR, CR, EPDM, butyls (IIR, CIIR, BIIR) to specialty and high performance elastomers such as silicone, fluorosilicone and fluoroelastomers (FKM).

Ames also develops hybrid materials to accommodate the need for thermal and electrical conductivity. Our materials development and process expertise makes the difference between simply making a component that performs adequately and creating one that excels.

Ames specialized in a variety of molding processes such as injection molding, transfer molding, compression molding, and insert molding where common sense manufacturing protocol …developed thru the years of experience provides consistent and reliable products that meet customer needs.

Injection Molding

Injection molding is high precision process providing high productivity and lower cost. The un-cured compound is delivered to a heated mold under high shear from an injection barrel using a screw and/or ram. The ability of this process to elevate the temperature and reduce the viscosity of the rubber compound allows for thermoplastic flow and shorter cure cycle providing high precision molded parts.

Liquid injection molding (LIM)

Liquid injection molding is synonymous to silicone materials and since the material is in relatively low viscous form, this process allows for lower pressure injection molding providing even higher precision than conventional injection molding with high viscosity compounds. Another feature of the liquid injection molding is the capability for very fast cycle time and with molding at lower pressure, it provides for use of less rigid components making this process an excellent choice for many applications.

Transfer Molding

Transfer molding is a precision molding method where the preformed compound flows from a transfer cavity usually located above the actual part cavities through series of sprues. Transfer molding compared to injection molding provides limited flexibility to increase cycle time and material waste with the main advantage of requiring relative low cost tooling in relation to part shape complexity not easily doable with compression molding.

Compression Molding

Compression molding is the most simple and widely used molding method particularly in short run- low volume part requirements. In this molding process, the preformed material is placed directly in the mold cavity and compressed under hydraulic clamp pressure until the completion of the cure cycle. Compression molded parts possesses the least tolerance control with most flash. Besides relative low cost tooling, it has the advantage of processing relatively large/bulky rubber parts.

Outsourcing

Ames has had a great deal of success in taking on our customers' capitol equipment to accommodate their outsourcing objectives. Tooling and manufacturing equipment will be smoothly integrated into our existing plants and workflow. Our engineering and manufacturing personnel work closely with our customers to create a seamless transition.

Over the years Ames has consistently demonstrated the ability to ramp up to full production as quickly and efficiently as possible, providing our customers with an uninterrupted supply of products. As specialists in the field of elastomeric precision moldings, Ames also has the facilities and staff to accommodate your outsourcing needs.

Cryogenic Deflashing

Whereas some injection or transfer molded parts contains residual flash, Ames also uses cryogenic deflashing technique. This process selectively transform the thin rubber flash below its crystallization point and thru mechanical agitation, flashless molded parts are obtained.
