Mould Design

Our technical approach to
Injection mould design

At Hybster, the design of a plastic injection mould relies on a rigorous methodology, combining precision, technical analysis, and numerical simulation. This approach guarantees reliable moulds, optimised for production and compliant with quality requirements.

Innovation and advanced technologies

We use the latest generation of simulation software and 3D design tools to guarantee high-performance moulds tailored to the most complex requirements.

Durability and simplified maintenance

Our moulds are designed to last, with robust materials and technical solutions that facilitate maintenance and extend their lifespan, thereby reducing long-term costs.

Flexibility for varied projects

Whether for small series, large productions or technical parts, our approach adapts to each need, offering personalised and scalable solutions.

Rigorous traceability and quality control

Each stage of design and manufacturing is documented and controlled, ensuring complete traceability and compliance with the most demanding standards.

Part analysis and mould feasibility

Before any design work, we carry out an in-depth study of the part to be injected:
Geometry,
Thicknesses,
Sensitive areas,
– Tolerances and functional constraints.
– Appearance and aesthetic constraints

This analysis allows us to determine the technical feasibility and anticipate potential difficulties related to moulding, such as sink marks or warping risks.

Optimisation

Proposals / improvement of thresholds, joint lines and drafts

We define the Joint lines, the clearance angles and the injection points strategically to ensure easy demoulding and a flawless surface quality. This optimisation reduces defects such as flash, parting line marks, or internal stresses.

For complex parts, we integrate systems of drawers, mobile cores and specific ejection mechanisms. These solutions enable the creation of undercuts, clips, or technical areas without compromising production speed or mould reliability.

Rheology and thermal

Simulation of filling and cooling

Nous utilizamos des logiciels de injection simulation to analyse the behaviour of plastic in the mould : 

– Filling time,
– Pressure,
– Temperature and cooling.
Anticipation of deformations

This step is essential for anticipating constraints, avoiding defects (shrinkage, bubbles, deformations) and ensuring stable production from the very first trials.

Frequently Asked Questions
Plastic injection moulds

Concrete assets for the success of your eco-designed projects

The choice of mould depends mainly on the production volume and the complexity of the part. For prototypes or small batches, an aluminium mould is often recommended. For medium batches, pre-hardened steel offers a good compromise between cost and durability. For intensive production or technical parts, a hardened steel or two-material mould is ideal.

The manufacturing lead time for an injection mould varies depending on its complexity and technical options (slides, insert moulding, multi-cavities).
On average, allow between 4 and 12 weeks, including design, manufacturing, and testing.
Urgent projects can be expedited through specific solutions.

The lifespan of a mould depends on the material used and the production volume.
An aluminium mould can achieve a few thousand cycles, whereas a treated steel mould can exceed several million injections.

Regular maintenance significantly extends the mould's lifespan.

At Hybster, the mould we design for you is your property. You have complete freedom to use it, transfer it or adapt it to your future needs. This transparency is a strong commitment to our clients.

Yes, it is possible to modify an existing mould, subject to technical feasibility.
The modifications can concern the geometry of the part, the addition of drawers or adaptation to a new material.
A preliminary study is necessary to assess the cost and impact on performance.

Yes, Hybster can rely on qualified partners in China for certain projects, while guaranteeing technical monitoring, quality controls, and validation before delivery. This approach allows for a combination of competitiveness and reliability.

Manufacturing moulds in China can be attractive for reducing initial costs, particularly on high-volume projects. However, it is essential to consider quality, transport times, technical communication, and compliance with standards. A comprehensive analysis of the total cost (including logistics and maintenance) is recommended before making a decision.
