The Penta Proven Process is the backbone of our quality. It’s a step-by-step system that governs how we estimate, prepare, manufacture and inspect every part. It removes guesswork, reduces variation and ensures we’re always working to the same high standard — no matter the job.
Once you get in touch with your requirements, we’ll arrange a call to understand your requirements and technical needs. You’ll learn more about our capabilities and how we can best support you.
Our experienced engineers gather technical information, offer design for manufacture suggestions if needed, and prepare a quote with transparent pricing and realistic lead times.
After placing your order, we carefully review the specifications and plan materials, tooling and resources upfront. Where helpful, we suggest design improvements to enhance manufacturability and avoid delays.
We turn plans into precise parts, maintaining quality and consistency across every production run. Our skilled team and modern CNC machinery ensure reliable results for both simple and complex parts.
After your parts complete our thorough final inspection process, your order is carefully packed and dispatched to your requirements. We provide comprehensive documentation for traceability and offer flexible delivery options, including stock holding, call-off, and Kanban services.
After delivery, we stay close. We review performance, capture lessons learned and proactively recommend tweaks that improve quality, value and lead times on your next run.
Quality at Penta is never a single step. It is a continuous process that runs through every stage of the Penta Proven Process, from reviewing your enquiry to delivering your finished parts. Each step is designed to maintain precision, consistency, and full traceability so you can be confident your order will meet the standards you expect.
This commitment is part of our culture as much as our process. Regular reviews, structured improvement projects, and a focus on training keep our team aligned on one goal: delivering exceptional quality every time. By embedding quality into the way we work, we give our customers peace of mind that their critical components are in safe hands.
ISO 9001:2015 accreditation means our quality management system meets internationally recognised standards. It ensures we have consistent processes in place for delivering high-quality parts, continuous improvement, and customer satisfaction.
JOSCAR (Joint Supply Chain Accreditation Register) accreditation means a supplier has successfully completed a comprehensive vetting process in the aerospace, defence, and security sectors to demonstrate they meet stringent quality, compliance, and security standards. This accreditation acts as a trusted, centralized record of pre-qualified suppliers, allowing buyers to efficiently verify potential partners and saving time and resources on due diligence.
Quotes are based on material, complexity, quantity, and any secondary operations or finishing requirements. We also factor in setup time, tooling, and delivery. If there’s a more cost-effective way to achieve your spec, we’ll advise during the quoting process.
