Why choose a custom-made insert?

A custom insert addresses specific technical challenges such as complex shapes, demanding environments, aesthetic requirements or high mechanical strength. It ensures seamless integration into the final product.

What are the benefits of a made-to-drawing insert over a standard insert?

A made-to-drawing insert is precisely tailored to the part, improving mechanical strength and simplifying the assembly process. It avoids compromises of standard models and enhances overall product performance.

What materials are used to manufacture custom inserts?

Inserts can be made from brass, stainless steel, zinc-plated steel or aluminum. The material is selected based on required strength, environment (humidity, temperature), and compatibility with the base material.

What are the steps to design a custom insert with SECAM?

The process includes: need analysis, 3D modeling, prototyping, validation tests, and series production with quality control. SECAM supports the customer throughout the entire development.

Can you manufacture custom inserts in small series?

Yes, SECAM offers small series production of custom inserts starting from a few hundred pieces, for prototyping, pre-series, or niche technical production.

How is technical compliance of a custom insert ensured?

Compliance is guaranteed through dimensional drawing validation, mechanical testing, material controls, and quality reports. Initial samples can also be provided for approval.

What is the typical lead time for designing and manufacturing a custom insert?

Lead time is usually 3 to 6 weeks after technical drawing approval. This includes modeling, prototyping (if needed), and series production.

Customized according to drawing

Q: What is a custom insert made to drawing?

A custom insert is a fastening part designed specifically from a technical drawing. It provides a perfect fit to the constraints of a plastic, metal or composite part, ensuring reliable and long-lasting fastening.

Custom inserts made to drawing
A tailor-made technical solution

Each industrial project presents its own mechanical, geometric or aesthetic constraints. To meet these specific requirements, SECAM designs and manufactures custom inserts made to drawing, fully tailored to your part or assembly process.

Whether you need a moulded-in insert with a custom shape, a screw-in insert for a tight space, or a technical insert in a specific material (stainless steel, aluminium, reinforced brass), our engineering team supports you from functional analysis to serial delivery.

A co-design approach with our engineering office

The development of a custom insert begins with a listening and analysis phase. Our engineers work directly with your design team to understand:

Mechanical constraints (tension, compression, vibrations, shear…)
Assembly conditions (moulding, overmoulding, screwing, heat insertion…)
Materials used in the part (plastic, resin, metal, wood…)
Acceptable tolerances and dimensions
Target production volumes

With strong expertise in fastening engineering, SECAM provides you with technical, cost-effective and industrial solutions.

When should you consider a custom insert?

Custom inserts are recommended when standard ranges do not meet a critical constraint. Typical cases include:

Special shapes to fit into non-standard cavities
Precise dimensions not covered by standard product lines
Enhanced sealing or specific surface treatments
Assembly in composite or technical materials
High-value parts requiring hidden or flush-fastening

Our goal: to design an insert fully integrated into your product – without unnecessary cost or complex adaptation of your tools or processes.

Full support from prototype to production

SECAM supports you at every stage:

Needs analysis and technical feasibility
3D design and insert modelling in its environment
Rapid prototyping via machining or metal 3D printing
Performance testing (pull-out, torque, ageing)
Series production with material and dimensional quality control

This rigorous process ensures an insert that meets your expectations, even for medium or low volumes.

Custom inserts for every type of installation

Our made-to-drawing inserts can be designed for all processes:

Overmoulded: custom geometry for maximum grip in injection moulded plastics (see standard range)
Screw-in after moulding: custom thread and knurl for enhanced pull-out performance (view our screw-in models)
Press-fit, heat, or ultrasonic: inserts optimised for automatic insertion
Expansion type: ideal when access is limited

We adapt geometry, thread type, material and surface finish to your specific constraints.

Available materials and custom options

Our custom inserts can be manufactured in a wide range of materials:

Standard or high-performance brass
Zinc-plated or stainless steel
Technical aluminium
Bi-material inserts or with built-in secondary components

Surface or heat treatments can be added to enhance corrosion resistance, friction behaviour, or other technical properties.

Examples of custom insert applications

SECAM’s bespoke inserts are used in demanding sectors:

Automotive: sensors, interior trim, structural assemblies
Electronics: connected housings, component mounts
Medical: single- or multi-use devices requiring sealing
Furniture: invisible fasteners for design-driven parts
Plastic industry: technical overmoulding, shrink-sensitive parts

Our ability to produce reliable inserts in small and medium batches makes SECAM a trusted partner for complex projects.
