Test bench for chrome plating on fittings and accessories
The chrome plating test bench on taps assesses the quality of the plating by simulating extreme environmental conditions to test its resistance to sudden temperature changes.
THE SOLUTION PROVIDED BY LF TECHNOLOGIES
Main functions
Objective
Design an endurance test bench to check the quality of the product’s coating, particularly its ability to withstand thermal shocks.
PROBLEMATIC ISSUES
- Speed pf testing
- Easy to install
- Control of dive times and number of cycles
- Limitation of test energy consumption
- Precise temperature control
- Need to carry out tests with or without water circulating along the walls of the product
SOLUTION AND RESULT
The bench consists of two tanks: a hot tank and a cold tank. Each tank is temperature-controlled. Two stainless steel baskets are attached to a pivoting arm. The baskets are divided between the vats: one basket in the cold vat and one basket in the hot vat.
When the adjustable delay has elapsed, the arm rises to lift the baskets out of the water and rotates through 180°. This movement allows the baskets to move from the cold tank to the hot tank and vice versa.
This principle means that twice as many products can be tested in the same amount of time.
Other advantages of our solution :
- Heating and cooling capacities designed to ensure good temperature control and rapid test preparation time
- Vessel design allowing testing in stagnant water or with flowing water around the product
- Ergonomic product installation
- Software ergonomics and ease of use
- PC control with various pre-recorded test protocols
Tested product
Sanitary taps with chrome coating
Sanitary taps with chrome coating, especially for use in saunas and steam rooms, hospitals, etc.
When used in saunas and steam rooms, the faucet is subject to high temperature and humidity variations. In hospitals, the hygiene conditions sometimes require cleaning the taps at a very high temperature.
These temperature variations lead to variations in the expansion of the products, which can cause cracks and delamination of the lining.
