From concept to producible product

Custom-Made plastic components

Whether you need a single prototype, a pilot series or larger production volumes: having custom plastic parts made requires expertise in material selection, engineering, manufacturability and scalable production. At PEZY we bring design, plastics engineering, prototyping and production together under one roof. This ensures components that are technically sound, cost-efficient and ready for the market — with minimal risks and iterations. PEZY manages the entire process: from concept and engineering through mold making, validation and series production. Everything takes place in our own facilities in Groningen or through our carefully selected partner network.

Analysis: the foundation for perfect plastic parts

The basis of a successful plastic component

Every project starts with a thorough analysis of the application, loads, environmental factors, user requirements and cost objectives. We combine your domain knowledge with our more than 30 years of experience in plastics engineering. This prevents costly surprises later in the process and results in a robust, manufacturable and future-proof product.

Companies often come to PEZY with a good idea or a technical concept. By linking this knowledge to our integrated plastics expertise, we create an efficient development process with minimal iterations and risks.

We dive deep early on into all the critical aspects that determine the success of your plastic components:

Usage Scenarios and Ergonomics

How is the part used in practice? Which forces, movements, contact points or repetitive actions are involved? We design for intuitive use, comfort and long service life.

Environmental Conditions

Temperature fluctuations, moisture, chemicals, UV radiation, vibrations, dust or impact — from day one we take the real-world conditions into account in which the component must perform.

Loads and Mechanical Requirements

Static or dynamic loads, pressure, bending, torsion or fatigue? Using simulations (FEA) we predict behaviour and optimise wall thicknesses, rib structures and material choice.

Production Volume and Cost Objectives

From 1 prototype to small series (100–5,000 pieces) or higher volumes? We immediately select the smartest production route: 3D printing, CNC, vacuum casting, rapid tooling or injection moulding. This determines both cost price and lead time.

Integration with Other Components

Seamless fit with electronics, mechanical parts, seals, connectors or other plastic components. We engineer everything simultaneously for perfect tolerances and easy assembly.

Sustainability and Circularity

From the analysis phase we already consider recyclability, recycled materials (PCR), biobased plastics and Design for Recycling. This way your parts not only meet technical requirements, but also growing sustainability standards.

Standards and CE Compliance

From day one, we incorporate all relevant standards and regulations into the development process. Whether it concerns IP protection, flame retardancy, food safety, medical guidelines (ISO 13485), RoHS, REACH or other sector-specific requirements: we ensure your plastic components are compliant right from the start. This minimises risks, prevents expensive redesigns and significantly accelerates certification and market launch.

PEZY develops plastic components for various markets (from industry and consumer electronics to healthcare and food) that not only excel technically but also fully meet the strictest European and international requirements.

Safety and Protection

From the concept phase we incorporate protection ratings such as IP65/IP67 (dust and water tightness), mechanical impact resistance (IK ratings) and flame retardancy (UL 94 V-0 or equivalent). This ensures your components operate safely even in the most demanding environments.

Environmental & Chemical Compliance

RoHS and REACH compliance are standard in our material selection. We actively avoid restricted substances and prioritise low-hazard, fully traceable plastics — essential for EU export and customers with high sustainability and supply-chain standards.

Sector-Specific Certifications

Medical devices follow ISO 13485, food-contact parts meet FDA and EU 10/2011 requirements, and industrial products comply with relevant sector directives. Early integration of these standards makes validation and certification significantly smoother.

Certification & Risk Reduction

We manage the full certification journey — from risk analysis and technical documentation to cooperation with accredited test labs. The result is a predictable, efficient process and a product that is market-ready faster.

From Concept to Manufacturable Product

We turn your specifications into a technically sound and visually appealing design, fully optimised for production.

Key focus areas when manufacturing custom plastic parts:

Optimal wall thickness and rib structures
Tight tolerances and perfect fit
Injection gate positions and venting
Surface finish and colour
Assembly and service friendliness
Design for Manufacturing (DFM)

By engineering the complete system in parallel — housing and functionality together — we deliver efficient, robust and production-ready plastic components.

Material Selection & Circular Solutions

The right material choice defines strength, weight, durability and cost. PEZY recommends high-performance plastics such as ABS, PC, PP and PEEK, alongside circular and biobased alternatives.

Using our Design for and from Recycling methodology, we develop components that are easy to recycle at end-of-life.

Technical plastics
Aluminium and other metals
Composites
Circular & recycled plastics

Prototyping & Validation

Before series production, we thoroughly validate your plastic parts in our own Pilot Factory in Groningen. This critical phase eliminates risks, optimises the design and confirms real-world performance. Our integrated in-house approach enables fast iterations and prevents costly mistakes later.

We rigorously test prototypes on:

Mechanical Strength & Functionality

pressure, bending, drop and fatigue testing.

Dimensional Accuracy & Tolerances

verified with advanced metrology equipment.

Surface Quality

texture, gloss, colour consistency and defect analysis.

Assembly & Fit

integration with electronics, seals and other components.

Thermal Performance

expansion, shrinkage and heat management.

Real-World Durability

climate, chemical, UV and vibration testing.

Tooling & Series Production Preparation

After validation we optimise the design for injection moulding and develop high-quality moulds that deliver from the first shot. We combine simulation expertise with our in-house mould shop and Pilot Factory.

In-House Mould Shop

In our fully equipped mould-making facility in Groningen we design, build and maintain all moulds in-house. This gives us short lines of communication, rapid iterations and complete control over quality and delivery times.

Fast Iterations

Our integrated approach allows us to adapt designs at lightning speed based on simulation results or test runs. All changes are implemented during the engineering phase — never during costly production runs.

Golden Sample as Reference

We produce and thoroughly validate a final Golden Sample in our Pilot Factory. This serves as the definitive benchmark for tolerances, surface quality, colour and functionality for the entire production series.

Scale-Up Support (Netherlands or Asia)

Whether you prefer local manufacturing in the Netherlands for maximum flexibility and short supply chains, or high-volume production with trusted partners in Asia — we manage the complete transfer. This includes full technical documentation, first article runs and strict quality assurance.

Creating Successful Plastic Components Together

Having your plastic parts made at PEZY means a single point of contact, short communication lines, high quality and a strong focus on circularity and manufacturability. From complex precision components to robust housings — we make it possible.
