Contract Manufacturing Services
Our materials and products maintain a proven reputation of quality and performance in the oil industry.
Tooling, fixtures, gauges, molds, presses, and special proprietary equipment are designed and built in-house.
We have a proven track record of working directly with our customers and their associates to meet and exceed project goals. Our primary concerns are to bring to market a high quality product to specification within designated time restraints. We manage the complete manufacturing process for our customers. All projects are well received and the upmost attention is given toward all project requirements.
Composite material fabrication, precision machine work, and product assembly are performed in-house.
We have proprietary adhesive techniques for metal-composite-rubber sealing using our void-free resin system. Rubber mandrel wrapping services may be performed in-house or outsourced to an approved vendor.
We have the machining capacity to ensure on-time delivery, and our machining capacity is continually growing. Our manufacturing facilities cover over 83,000 square feet with over 100 machines. We utilize:
- Over 60 machines at our main facility with capabilities of machining composites, rubber and metal materials,
- 25 machines at a second facility specializing in the machining of large metal parts and complex features,
- 18 machines at a third facility specializing in the machining of composites,
- 41 composite fabrication machines.
Our precision machine shop guarantees excellence in workmanship of machined parts.
Our machining capabilities include:
- Small and large part machining of parts up to twenty-five feet in length
- Complex feature machining utilizing our five and six-axis mills or highly accurate turn-mills
- Wire and Plunge EDM work
- Offset mill and lathe work
- Gun drilling
Various material machining
Our material machining experience includes, and is not limited to: Composite Materials, Stainless Steel, Inconel, P 550, Beryllium Copper, Titanium, Tungsten, Stellite, 4140-series Steel Metals, Rubber, and Plastics.
We cut a full range of internal and external threads in-house. Our in-house threading experience includes: API, ACME, and UNC type thread work. We frequently cut stub, buttress, fine, double lead, taper, and straight threads. We outsource inspection of API type threads and the machining of various premium threads including, but not limited to: VAM, and Tennaris Hydril threads.
Our in-house machine shop is capable of delivering high-volume production orders of up to 35,000 parts per month. Our machining capacity is continually growing to produce larger order quantities upon our customer’s requests.
We will gladly work with your engineers through prototype development and production runs to ensure parts and instruments are manufactured to design requirements. It is of upmost importance to us that all products and manufacturing processes remain confidential.
We have extensive experience and knowledge in part repair and restoration of downhole composites and metal instruments. Repair and restoration projects are determined on a case-by-case basis following inspection of the part at our facility.
Local Pick-up and Delivery
We provide pick-up and delivery services of products within a fifty mile radius of our Sidney location.
We will work with your engineers to provide our knowledge and expertise with our composite materials. We have on staff multiple registered professional engineers with hands-on experience in utilizing technology and materials suitable for downhole, geophysical, aerospace, marine, and chemical use.
We maintain an approved vendors list for all outside processes. Through our local network of vendors, Keystone ensures turnkey products requiring outside processes are delivered to customers on-time with the highest quality of workmanship.
We outsource surface treatments such as laser cladding for wear parts, shot peening of metals, phosphate coating, galvanizing, and plating of Nickel, Gold, and Silver.
Welding and Brazing
For critical hermetic welds that are Helium tight to 10-9cc/ sec, we utilize computer controlled Laser and an Electron Beam. These processes are provided by our affiliate company and used when assemblies call for close tolerances, dissimilar metals, or thin wall sections. Induction brazing and oven brazing are available. TIG and Plasma welding are used for non- critical applications.
Non Destructive Testing
Composite materials are tested for defects using non-destructive testing techniques at an outside vendor.
