With an extensive collection of tools and technology, Sturm is able to design and modify parts, cast and heat treat on site, machine the part, and inspect the part with accuracy and precision.
An on-site customer service department will assist customers by providing quick and accurate parts data. The customer service team can provide pricing for parts and lead times by gathering basic information from the customer including shape, size and material of the part.
The engineering department plays a vital role in the parts manufacturing business. With full reverse engineering means and design capabilities that include hydraulic and mechanical modifications, the engineering department is able to help solve customer problems.
Data acquisition is carried out using coordinate measuring machines (CMMs). Sturm has four FARO CMMs on location, which allow onsite data acquisition. These machines have articulated arms that gather three-dimensional data within a six foot sphere, and allow the obtained dimensions to be repeatable to within 0.001".
Sturm PMC has a dedicated server for electronic drawing storage and access. The database includes over 300,000 drawings, complemented with over 400,000 customer inventory records.
The foundry at Sturm PMC is capable of pouring alloys with various technologies including conventional no bake sand, rapid prototype ceramic shells, centrifugal molds and the newly added multi-axis CNC robot sand mold. The foundry is set up to pour castings ranging in weight from 301 pounds to 1000 pounds.
In addition to pouring castings, the foundry offers additional support services to meet customer demands. Sturm can provide a customer with heat treatment, certified material test reports and chemical analysis. The facility can also perform a number of tests on material and products including:
- Hardness testing
- Tensile testing
- Hydro testing
- Liquid penetrant testing (through a certified contractor)
- Wet/dry magnetic particle testing (through a certified contractor)
- Non-destructive testing (NDT) (through an outside accredited lab or contractor)
- Impact testing (through an outside accredited lab or contractor)
As mentioned, Sturm is capable of providing molds in four different way. They are as follows:
- No bake sand
- Wood patterns (customer supplied or new development)
- Flask sizes ranging from 14" to 60"
- Rapid prototype (ceramic shell)
- Rapid prototype molds
- Casting sizes ranging from 16" square to 8" in height
- Supported by on-site part modeling
- CNC robot sand machining
- 5-Axis CNC robot for sand molding machine
- Utilizes standard flask sizes
- Supported by on-site part modeling and programming
- Centrifugal casting
- Sleeves ranging from 3" to 16" in diameter and up to 48" in length
The machine shop at Sturm PMC uses both CNC and manual equipment to manufacture pump parts. A recent investment of over $2 million allowed Sturm to upgrade and modernize the machines and equipment in order to meet customer's needs and requests in an accurate and timely fashion.
Sturm produces a wide variety of turned, milled and ground components. CNC lathes and mills contribute to the reliability and accuracy in machining several parts, including shafts, sleeves, impellers, suction covers, and diffusers, among several other critical service components. Sturm PMC is capable of machining parts to very high tolerances, meeting the most demanding of applications. Parts that meet military specifications and parts for high energy applications can also be produced at Sturm PMC.
