10 questions/answers about HLOCK: The high-performance solution for securing threaded fasteners
1. What is HLOCK V2 and what does it do?
HLOCK est une gamme innovante de frein-filet sec développée par Soprima Industrie, spécialement conçue pour le freinage des fixations filetées dans des secteurs de haute précision tels que l’horlogerie, la lunetterie et la joaillerie.
Cette solution empêche le desserrage des vis provoqué par les vibrations ou les chocs, assurant ainsi une sécurisation optimale dans des applications où la précision est primordiale.
Deux des produits de la gamme sont désormais proposés en version V2, avec des améliorations notables, notamment une date limite d’utilisation (DLU) prolongée et une durée de polymérisation optimisée à deux ans . Le troisième produit conserve sa formule d’origine, déjà éprouvée.
2. What are the different HLOCK versions and their features?
The HLOCK range comprises three main products:
- Two microcapsule-based products:
HLOCK 2510-V2 (orange) and HLOCK 2353-V2 (blue): Bonded locking systems, usable 1 to 2 times. - A polyamide-based product:
HLOCK Polyamide (green): Repositionable locking, usable up to 5 times, particularly suitable for applications requiring frequent adjustments.
3. How does HLOCK technology work?
HLOCK technology is based on two principles:
- Microcapsule-based products: When the threads are pre-coated with these microcapsules and the screw is fitted, the capsules burst, releasing the adhesive contained. This adhesive polymerizes rapidly, forming a strong bond between the elements.
- Polyamide-based product: This adhesive is renowned for its ability to form strong bonds thanks to the hydrogen bonds between its polymer chains, ensuring excellent adhesion to a variety of substrates.
4. What type of parts can HLOCK be used on?
Soprima Industrie has a range of machines developed in-house, enabling us to process a wide variety of parts from Ø0.7 upwards.
5. What are the specific advantages of HLOCK for the luxury sector?
- Optimum locking: Effective protection against vibration and shock.
- Preservation of aesthetics: The solution preserves the appearance of parts, an essential criterion in the luxury sector.
- Precious metal compatibility: Ideal for materials such as gold and platinum.
- Adaptability: Designed to meet the exacting technical specifications of each assembly.
6. What are HLOCK's applications?
The Hlock range is used in:
- Fund screws
- Eyeglass screws
- Deployment buckle screws
- Bracelet screws
- Eyewear and jewelry
- …
7. What's the difference between HLOCK and other locking solutions?
Unlike traditional solutions (liquid threadlocker), Hlock offers:
- Uniform application thanks to pre-coating.
- Activation during screwing only, eliminating any risk of human error.
- Excellent resistance to vibration while preserving part aesthetics.
8. What is the shelf life of HLOCK pre-coated screws?
HLOCK pre-coated and unassembled products have a shelf life of 2 to 4 years when stored at room temperature, between -10°C and 35°C. This long shelf life represents a considerable asset for workshop and subcontracting inventory management.
The lifespan of assembled parts is infinite.
9. Are PFAS present in the products?
