Custom Solutions Engineered for Real Production Demands.
When standard masking products are not the right fit, EPSI develops custom masking solutions engineered around your part geometry, finishing process, and production requirements. From application review through prototype validation and production planning, EPSI helps customers move toward a more effective, repeatable, and scalable masking solution.
The EPSI Guarantee
The EPSI Guarantee means recommending the best-fit masking solution for your application. Sometimes that is a proven in-stock product. Other times, it means a custom-engineered solution designed to improve coverage, reduce labor, support consistency, and protect critical surfaces more effectively across demanding finishing environments.

Why Custom Matters
EPSI isn't just a parts supplier, we are a true process partner here to design the path from application problem to engineered solution, while reducing friction for customers who need fast answers, stronger validation, and better production economics.
- Engineered Around Your Application — Solutions developed around your part geometry, finishing process, and production requirements.
- Repeatable Production Performance — Custom designs built to improve consistency, reduce labor, and support scalable production.
- Cost Justification That Matters — Clear evaluation of when a custom solution becomes more efficient than manual masking.
Engineered Around Your Application
EPSI works closely with customers to design masking solutions around actual production requirements, part complexity, finishing method, and performance expectations across coating, plating, anodizing, painting, and related processes.
Faster Prototype Validation
With the EPSI Formlabs Form4 3D printer, customers can receive prototype parts for form and fit evaluation in as little as two days, helping accelerate design decisions and reduce project lead time.
Cost Justification That Matters
EPSI can help determine when a custom molded solution becomes more cost-effective than masking by hand, clarifying the labor, consistency, throughput, and long-term value case behind the recommendation.
Where Engineering Creates Better Outcomes
Custom masking is not just about making a unique part. It is about improving the way your operation performs. EPSI helps evaluate part geometry, masking coverage, critical surface protection, handling, labor intensity, repeatability, and total application fit so the final recommendation works in production, not just in theory.
- Review the part, process, and finishing environment
- Identify whether in-stock, prototype, or custom is the best path
- Validate form and fit earlier to reduce downstream risk
- Improve process consistency and reduce masking variability
- Support production teams with a more repeatable masking method
Practical Solutions for Complex Parts
EPSI custom solutions are designed to support real-world production performance, whether the challenge is geometry, sealing, handling, part protection, or the need to reduce manual masking effort across higher-volume work.
From Application Review to Production Fit
Engineering support is critical when you need a clear path that reduces uncertainty, validates the concept, and delivers a repeatable production solution.
Review the Application
Start with the part geometry, critical surfaces, finishing process, handling needs, and production goals.
Choose the Right Path
Determine whether an in-stock product, a rapid prototype, or a fully custom solution is the best fit.
Validate Form & Fit
Use prototype feedback to confirm geometry, sealing, handling, and application performance before scaling.
Move Toward Production
Align the final solution to labor reduction, repeatability, throughput, and stronger finishing performance.
From In-Stock to Fully Custom
Not every application requires a fully custom molded solution. EPSI helps determine the right level of solution based on the part, process, timeline, and production volume.
In-Stock Product
Best when a proven standard part can protect the feature effectively with speed, availability, and minimal engineering lift.
Rapid Prototype
Best when geometry, fit, sealing, or handling needs to be validated quickly before committing to full production tooling.
Fully Custom Solution
Best when production consistency, labor reduction, performance, and application-specific requirements justify a tailored part.
Custom silicone masks, plugs, and specialty components designed around specific finishing requirements.
Engineering-led development supports cleaner validation, faster iteration, and a stronger path to production.
