Types of anodizing:  Type I Anodizing - Chromic Acid also known as CAA or Chromic Acid Anodize.  Type II Anodizing - Sulfuric Acid or Sulfuric Acid Anodize SAA.  Type III Anodizing - Hard coat or  Hardcoat Anodizing HCA.

The Walgren Process is a powerful collaboration between Walgren engineers and customer representatives. This unique protocol, refined over more than 60 years, produces success at each benchmark.

It also results in the commissioning of an efficient finishing system that delivers the consistency, throughput and flexibility the customer specified, on-time and on-budget.

The Walgren Process

  • The Walgren Process begins with our investment in time and resources to understand each customer's specific products, facility, working culture, and short and long-term priorities. During this stage, we work with customer representatives to outline the applicable process steps, line layout, loading and unloading of parts, material handling requirements within the line, (as well as up and downstream) sizing, controls, and environmental issues.
  • Based on our findings, Walgren technicians generate two preliminary documents: a design production analysis, and design process spreadsheet. Informal discussions and clarifications then lead to the creation of a comprehensive design layout with elevation drawings.
  • In the next step, equipment is selected and sized, and a quotation is produced. Customer comments then lead to refinement and clarification of various proposal elements before final approval.
  • Once a project is approved, an internal Walgren project “kick off” meeting is scheduled, where timeline requirements and milestones are specified, and assigned to project team members.
  • During the engineering phase of a project, engineers and designers collaborate on system design, and specify all components. All drawings are subject to an extensive internal checking process prior to their release to manufacturing to assure ISO and NADCAP compliance.
  • The pre-production drawing package generated by Walgren includes the line layout, elevation view, roof openings, concrete requirements, utility tie points, and PID drawings. This package is provided to the customer for comment and approval. Once drawings are approved, bills of material are released for the purchase of raw materials and for direct-buy items to be shipped directly to the customer site. (If needed, all components can remain at Walgren Company for customer review and approval before shipment.)
  • Installation begins after manufactured items are complete and the facility is ready. Depending on the project size, equipment may ship to the job site all at once, or in stages to complement the installation sequence. Walgren contracts worldwide with three highly knowledgeable installation crews that specialize in the installation of Walgren-built finishing systems. To assure the installation proceeds exactly as outlined, an experienced installation manager remains onsite throughout the installation process.
  • The last phase of the project is commissioning and worker training. Our controls engineer and installation manager test every system component and document all pertinent settings. All material handling equipment is cycled multiple times and inspected for anomalies. Once the system is commissioned, operators receive both classroom and “hands on” training.
  • Preventative maintenance contracts are available for short or long terms. Most customers use Walgren PM contracts to train their own maintenance personnel and take over this responsibility gradually, over time.
