Processes

Skilled and dedicated people are the key to creating good quality castings. Because each and every casting is unique, consistent quality is the product of understanding the customer’s casting requirements, knowing the variety of process variables, defining and documenting the parameters.

Our system begins when our sales engineering team works closely with the customer to define the casting’s requirements. Meeting our customers’ delivery due dates is of critical importance to us. We agree on what is required and achievable at the time the order is received.

Then, our most experienced workers create the tooling and develop the production process, which includes tracking the progress of every order and keeping you informed of your order’s status. We recognize that some orders demand a “rush” response, and we make every effort to expedite deliveries if necessary.

Permanent Mold

Permanent Mold

Our process know-how comes from years of hands-on experience producing castings for demanding markets and industries that require extensive coring and must meet high standards for porosity, pressure tightness, and machinability.

Our variety of permanent mold machines offer the flexibility and capacity for production runs – small and large, with tighter dimensional tolerances, and a superior surface finish than sand castings.

Sand Casting

Sand Casting

Our multiple lines and skilled molders provide considerable capacity and flexibility to support low- and mid-volume sand casting production.

We can turn your plastic 3D printed parts into prototypes or very low volume production parts in just a few days.

At Ermak we have both Green Sand Molding, and No-Bake Sand Molding allowing for more complicated, and extremely large castings. The No-Bake process is used for castings that require deep pockets, or have limited draft situations.

Machining

Machining

Our machine shop is equipped with CNC Lathes, CNC Vertical Milling Machines and supporting equipment . We work with stainless steel, steel, aluminum, brass, plastic, and castings.

Many of the products that we produce are for demanding applications that require pressure tightness and extensive machining. Our team of experts works hard to ensure that we meet or exceed your critical requirements.

Finishing

Finishing

Many aluminum castings require heat treatment to specific tempers. Our large high-temperature ovens, as well as our aging ovens, provide excellent tempering results that are consistent and reliable.

In addition to heat treating, our finishing process includes machining, painting, anodizing, polishing, grinding, and plating.
