Trusted by aerospace suppliers across the UK, we deliver high-tolerance, ISO 9001 certified CNC machined components with full traceability and consistent reliability.
Penta Precision delivers trusted aerospace machining services to UK aerospace suppliers who demand precision, reliability, and compliance for their parts. With over 25 years of experience in CNC machining for aerospace applications, we produce high-tolerance components with repeatable accuracy for both development and production needs.
Our ISO 9001 certified processes ensure that every aerospace CNC machining project meets strict industry standards, while full traceability and clear documentation simplify audits and quality checks. We specialise in non safety-critical aerospace parts for airplane interiors, supporting clients with prototypes, small-to-medium batch runs, and time-sensitive projects that require dependable delivery.
From tight-tolerance aluminium parts to engineering plastics and titanium components, we provide flexible machining capabilities and exceptional service that streamline your supply chain.
Partner with a team that understands the complexities of aerospace manufacturing and delivers consistent quality you can rely on.
CNC machining is widely used in aerospace to manufacture both structural and non-structural components.
At Penta Precision, we specialise in non-critical interior partssuch as seat mechanisms, cabin fittings, bracketry, housings, and trim components.
These parts require consistent precision and high-quality finishes to meet the performance and cosmetic standards of aerospace interiors.
We focus on non-critical internal aircraft partstypically found inside the cabin.
These include seat frame elements, armrest brackets, tray table components, internal housings, and ventilation or panel fittings.
These components are essential for passenger experience and require high repeatability and clean, burr-free finishes.
Internal aircraft parts must be lightweight, durable, and manufactured to exact specifications, often with tight tolerances and high aesthetic standards.
CNC machining delivers this precision.
Our CNC mills and lathes are ideal for repeat machining of interior components, ensuring quality and cosmetic consistency across batches.
Interior aerospace components are typically machined from materials like aluminium alloys (e.g. 6082, 7075), engineering plastics (such as PTFE, PEEK, and Nylon), and occasionally copper or brass for electrical housings.
Penta Precision's capability across both metals and plastics is a key advantage for customers requiring a one-stop solution for diverse interior parts.
We apply the same rigorous quality controls to internal aerospace parts as you'd expect for mission-critical components.
This includes in-process inspection, full traceability, and final inspection before dispatch.
Our ISO 9001 certification and customer-first approach ensure quality and reliabilityevery time.
Yes. We're well-suited to repeat medium-to-high volume production which is common in aerospace interior programmes.
Whether you're sourcing components for a cabin upgrade, a fleet interior refit, or an ongoing production line, we ensure consistency across batches and proactive communication to keep your supply chain flowing smoothly.
