The Clark Precision Machined Components’ Cold Drawn Steel Bar Division produces steel bar requirements to exact dimensions and tolerances for the company’s three machining divisions, as well as our outside customers.
Because of Clark’s extensive experience in the machining of steel, Clark has a first hand understanding of the needs of its outside bar customers. Let us put that experience and understanding to work for you. From controlled grain structure and hardness, to precision straightness and square cut bar ends, Clark’s cold drawn steel bars satisfy the most rigid demands of its cutting, forming and machining customers.
Clark’s Cold Drawn Mill draws most grades of carbon and alloy steel in round, hex, square, and other shaped bars, in sizes up to 3.5”.
We pride ourselves on providing consistent delivery matched to the customer’s requirements and schedules – including daily shipments as required.
Equipment
Clark Precision’s cold drawn steel bar equipment consists of:
- two shot-blast cleaning machines
- a 100,000 lb. mechanical draw bench
- a 75,000 lb. hydraulic draw bench
- two bar shears
- three dual-roll straighteners
- a shape straightener
- an eddy current test line
The Cold Drawn Steel Bar Mill operations are serviced by four 7-ton and three 3-ton overhead cranes.
The mill was newly built in 1985 and has received several upgrades and expansions since then.
Process
Clark has developed a unique proprietary cold finish process that consistently produces an extremely high level of repeatability in even the toughest cold finishing requirements. Areas of unique control techniques and processes include:
- Shot
- Draw oil
- Draw dies
- Draw die design
- Straightening process controls
Clark enjoys supply partnerships with numerous hot rolled bar mills throughout North America, assuring competitive pricing and alternative supply partners for uninterrupted delivery. And because we store 100% of our hot rolled raw material steel inside under controlled temperature and humidity conditions, Clark’s production and storage systems produce high quality trouble free surfaces.
Clark is also closely aligned with a number of leading heat treaters and other outside services. The latest heat-treat and anneal processes are used, which provides our customers with improved machineability and physical properties.
So if you have diameter, straightness or physical property concerns, make sure you ask for “Clark Drawn Bars!”
