Plastic product development: from idea to a perfect injection moulded production series

Having a successful plastic product developed starts with a thorough analysis in the very first phase. Many development projects get stuck or become unnecessarily expensive because functionality, manufacturability, cost price and production requirements are only considered late in the process. This often leads to adjustments, additional mould modifications or even a complete redesign.

PEZY takes a different approach. Your product idea is translated directly into a production focused design. From the concept phase onwards, technical feasibility, material selection, injection moulding optimisation and circularity are taken into account. This prevents surprises and ensures your plastic product is efficient, cost effective and ready for series production from the start.

We brengen in kaart hoe jouw product precies gebruikt wordt, welke krachten erop komen, in welke omgeving het moet functioneren en welke eisen de eindgebruiker stelt. Dit vormt de basis voor de materiaalkeuze en de constructie.

Whether you need 500 units per year or 50,000, the approach differs significantly. Development decisions are optimised from the very beginning for your target production volume, ensuring the best balance between cost, quality and manufacturability without surprises later in the process.

Snap fits, hinges, locking mechanisms, seals and direct electronics integration are incorporated into smart design solutions that reduce part count and significantly lower assembly costs.

Circularity is considered from the very beginning. Biobased materials, recycled plastics and Design for Recycling principles are evaluated to ensure your product not only complies with current regulations, but is also prepared for future sustainability requirements.

De juiste kunststof kiezen is bepalend voor de prestaties, kosten, duurzaamheid en het uiterlijk van jouw product. Een verkeerde materiaalkeuze leidt vaak tot hogere kosten, lange doorlooptijden of problemen in de seriefase. Bij PEZY helpen we je om die keuze gericht en onderbouwd te maken.

Material selection goes beyond mechanical properties. Chemical resistance, temperature range, flame retardancy, food contact, medical grade requirements and recyclability are also taken into account. This ensures the chosen material fits your application and your sustainability goals.

Material selection always starts with the technical requirements of the product. Strength, stiffness, impact resistance, creep behaviour and wear are assessed. Whether it is a robust housing component, a flexible snap fit system or a precision part with tight tolerances, the material must meet all functional requirements.

At the same time, special properties such as UV resistance, transparency, antistatic performance and flame retardancy are considered, including the required certifications such as FDA, UL and REACH.

Cost, availability and circularity are equally important factors. A careful balance is made between high performance engineering plastics such as PC, PBT and PA, and cost effective commodity plastics such as PP, PE and ABS. Increasingly, recycled (PCR), biobased or fully recyclable materials are recommended.
By applying Design for Recycling principles from the earliest stages, your plastic product is designed not only to perform today, but also to be efficiently recovered and reused at the end of its lifecycle.

We test whether all moving parts, snap fits, hinges and other functional elements work exactly as intended. By using real injection moulded parts, we identify potential weak points in the design that may not always be visible in simulations. This ensures the product is strong, reliable and user friendly in practice.

We optimise and measure cycle time down to the second. We also verify reproducibility across multiple production runs. This creates a stable process with minimal variation between parts. The result: efficient production with consistent quality and a lower cost per unit.

We measure gloss, colour consistency and critical tolerances using precise measurement equipment. Any sink marks, flow lines or other aesthetic and dimensional deviations are identified and resolved immediately. This allows us to deliver parts that meet the highest standards, both technically and visually.

Alongside technical measurements, we also test how the product performs in practice. Does assembly run smoothly? Does the final product feel right for the user? Are there any hidden issues during assembly or everyday use? This hands-on evaluation ensures that the product works not only on paper, but also in the hands of the end user.

Once the prototype has been fully validated, preparation for series production begins. This phase is critical to ensure a smooth, efficient and predictable transition from prototype to tooling and production. Every detail is optimised to ensure the first production run delivers the required quality and cost efficiency from day one.

The mould, injection moulding process and complete supply chain are thoroughly reviewed. This prevents downtime, quality issues and unnecessary cost increases during series production.

Final Design for Manufacturing optimisations are implemented to minimise cycle times, reduce scrap and maximise mould lifetime. The mould is then designed and built, or the process is fully managed on your behalf, based on your production volumes and performance requirements.

The first production samples are manufactured and measured down to micron level accuracy. A golden sample is then established as the reference product for all future production runs, ensuring a clear and consistent quality standard.

We deliver a set of approved samples along with a final golden sample. This acts as the definitive benchmark for series production. Every critical specification, tolerance and aesthetic requirement is clearly recorded, ensuring your production partner knows precisely what is expected.

Injection moulding parameters are fully optimised, automation and robotics are implemented where required, and measurement and quality control procedures are established. This includes PPAP, FMEA and any industry specific certification requirements, such as medical, food or automotive standards.

Packaging, labelling, inventory management and logistics are arranged. Intensive support is also provided during the first production series, including continuous improvement and cost down opportunities.
