First, the temperature of the saturated tank can not rise to the set temperature Fault causes: 1. Saturated barrel temperature controller temperature is too low; 2. Saturated barrel safety switch is set too low; 3. Heating system failure; 4. Electromagnetic relay failure; 5. Controller failure.
Treatment methods: 1. Set the temperature controller to the required temperature; 2. Set the safety switch to the desired temperature; 3.4.5. Inform the repair company to take care of the door.
Second, the compound salt spray test machine can not rise to the set temperature failure causes: 1. laboratory temperature controller temperature, set too low; 2. laboratory safety switch set too low; 3. heating system failure ; 4. Electromagnetic relay failure; 5. Controller failure.
Processing methods: 1. Set the temperature controller to the desired temperature; 2. Set the safety switch to the desired temperature; 3.4.5. Inform the repair company to take care of the door.

Pattern and Casting
Pattern will be made first and done inspected before casting.
Cast pieces are presented in the foundry, for inspection of dimensions and hardness after sandblasting and machining but before conservation and painting. Deviations are sanctioned as follows for example:
