At Chevalier Cleret ELTEC, we support players in the cosmetics sector in the development and industrialisation of LSR silicone parts that meet high standards of cleanliness and functional reliability.
The latest example is the development of an LSR silicone flat gasket component, which provides a sealing function on cosmetic packaging, industrialised using a semi-automatic 24-cavity LSR injection process.
An LSR silicone part designed to meet the requirements of the cosmetics industry
In the cosmetics industry, LSR silicone parts must meet several key requirements:
- Perfect sealing on sensitive interfaces
- Dimensional stability and repeatability in production
- Cleanliness of the process and parts
The flat seal developed is integrated into a cosmetic assembly requiring a reliable sealing function, while guaranteeing consistent quality in terms of appearance and performance.
Semi-automatic 24-cavity LSR injection: a suitable process choice
For this LSR silicone part, we designed and implemented a semi-automatic LSR injection process based on a 24-cavity mould.
This choice allows for:
- An excellent compromise between productivity and flexibility
- Precise control of LSR injection parameters
- Dimensional repeatability
- The possibility of increasing production rates if necessary
LSR injection remains particularly relevant for the manufacture of LSR silicone sealing parts, thanks to the stability of the material and the precision of the process.
Complete development carried out in 2.5 months
The project was carried out over a total period of 2.5 months, incorporating all the key stages:
- In-house mould design
- Mould production by approved subcontractors
- Receipt and dimensional checks of mould components
- Assembly and adjustment of the mould
- Mounting on LSR injection moulding machine
- Process testing and determination of optimum injection parameters
- Dimensional measurement of parts
- Updating of technical manufacturing data
- Presentation of initial samples to the customer
Mastery of LSR injection moulding: from development to production
This new project illustrates our ability to:
- Develop multi-cavity moulds suitable for the manufacture of technical LSR silicone parts
- Industrialise semi-automatic LSR injection processes
- Support our clients from the early stages of development
Our teams work on cosmetic, industrial, aeronautical, medical and automotive projects, for sealing and cushioning functions.
