Quality Control and Material Analysis

Our team ensures the highest quality product by understanding the metallurgy and quality expectations for all of our customers. At Col-fin, we take great pride in our absolute attention to these details.

The Met-Lab

The components of Col-fin’s Quality Control Process that are monitored on every order are:

  • Decarburization
  • Seam Defect Depth
  • Integrity of Internal Structures
  • Hardness Properties
  • Tensile Properties
  • Size and Dimensional Tolerances
  • Other Customer Specific Details  

Col-fin’s Met lab is well equipped to monitor product quality throughout the process. The focus of Met Lab testing and quality control parameters include:

  1. Hot Roll Raw Stock Check: Thorough inspection of the as-received hot rolled raw stock is conducted on all material. Coil ends are sampled and Hot-etched to detect seam defects. Microscopic evaluation follows with special attention to incoming decarburization, integrity of the internal structures and another look for seam and surface defects. Sample approval from the Met-Lab is required prior to continuing with any further processing.
  2. In-Process inspection: Once a product is in process, samples are cut and taken to the Met-Lab for evaluation. Structure, decarburization, seam and surface quality are reviewed and must be approved in order to proceede with any further manufacturing process.
  3. Final Inspection: Samples of the completed product are once again examined in the Met-lab. Final Met-lab approval must be given prior to shipment of the product. 
  4. Dock Auditing: Items scheduled for shipment receive a final review. Shipping personnel along with quality control management review the packaged material to be certain no detail has been overlooked and all outgoing products are within predetermined Master Controlled Customer specifications. 

Productivity Enhancement Program PEP

One of our principle objectives at Col-fin is to be certain we are communicating every aspect of our production capabilities. In so doing, we offer our customers PEP, which involves not only meeting with purchasing and administrative personnel, but also machine operators and plant supervisors. In such meetings, we get a better and more concise idea of the problems that the operators deal with on a day-to-day basis, and what can or might be done to alleviate such problems. 

Our objective with PEP is not to recommend change, but rather to educate the customer as to what is available from a product standpoint and what conditions are possible that can optimize their secondary operations. PEP meetings are available to our customers any time they feel that our sharing information might be beneficial to their in-plant processes.


Continuous Improvement

A key feature of the Col-fin process is our attention to continuous improvement and optimization.

This attitude at Col-fin is based upon the belief that no process is ever perfect and can always be improved upon in some way.

We are committed to searching for ways to optimize the quality and production of products, whether utilizing a new process to improve yields or by changing die draft angles to produce a more consistent surface on the end product.
