Custom Castings Case Study
| Material: | 356.1-T6 |
| Weight: | 1.8 lbs |
| Dimensions: | 6” x 3.5” x 3.5” |
| Applications: | Hydraulic filter adapter for hydraulic system on Bobcat Skid Steer Loaders |
- We used permanent mold, due to quantity needs and sand core requirements, which allowed us to consistently produce a product with a high level of internal complexity.
- To solve some of the production challenges posed by the complexity of the component—namely, deburring and internal cleanliness requirements—Custom Castings invested in equipment and training.
- We’ve produced 35,000 EAU. The program started in 2013.

Forte Case Study
| Material: |
P20 material , Ductile iron
|
| Weight: |
5000 lbs assembled
|
|
Dimensions:
|
4.5” x 25” x 53” each |
|
Applications:
|
Mold used in various manufacturing processes requiring high precision and durability |
- We used a multi-material build approach to balance durability and functionality for this mold. P20 tool steel was selected for the mold cheeks for its resistance to wear. A ductile iron core was used to facilitate sliding without binding or galling, enhancing the mold’s performance.
- We used two hydraulically actuated cylinders to move the pull core. We carefully designed and implemented the plumbing for these cylinders to ensure they were well-protected from the operational heat.
- The pull core was also designed with a hinge to flip up, allowing easy access for cleaning and spraying, ultimately improving maintenance.
With more than 25 years in the coating industry, Protek applies coatings for various industries, which protect products against the harshest materials.

Protek Case Study
| Client: | International Nutraceutical Company |
| Coating Type: | FEP |
| Problem Statement: | Reduce defective gel caps due to sticking |
| Product: | Manufacture Soft Gelatin Capsules |
- Problem: A major international nutraceutical company faced leaking gelcaps due to the condition of their existing wedges and needed a quick, long-term solution.
- Solution: After thorough testing, we recommended a lower friction, food-grade Teflon™ coating and established a pre- and post-QA inspection process with serial number tracking.
- Result: We improved operating performance, reduced maintenance downtime, and enhanced capsule quality, implementing a preventative maintenance schedule with a 24-hour turnaround, maintaining transparency and trust through detailed reporting.
