As the main means of transportation for our daily travels, the safety of automobiles has always been valued by consumers and manufacturers, and castings are one of the important components of automobile product parts.
thereforeWaterproofness and airtightness of automotive castingsIt is closely related to the safe driving of cars.

If the waterproof performance of the casting does not meet the requirements, it may cause huge safety risks.
For castingsAir tightness testing(Waterproof testing) is an important process before castings leave the factory.
Air tightness testing
When using the traditional water immersion test to test castings, contacting the product with water and subsequent drying is time-consuming, inefficient, and the production cost is too high. Therefore, many automobile manufacturers have given up testing the waterproofness of automobile castings with water.
With the development of waterproof detection technology, there has beenMore accurate、more effectiveofAir tightness testing, it is more effective and scientific than traditional water testing and will not cause secondary damage to the product.
Air tightness testing solution for automotive castings
According to customer requirements, this automotive casting needs to meetIP68waterproof level,
Hirays Technology uses the following equipment and solutions
Equipment used:Hai RuisiHC Classic Series Pressure Type Air Tightness Detector
Solution: Adoptdirect testmethod, test pressure30Kpa, inflation time 10S, stabilization time 15S, test time 10S, leakage upper limit30pa。
picture2-1 Casting inspection parameters
Design the mold according to the shape and structure of the casting, and use the mold to seal the holes and upper and lower bottoms of the casting to form an internalsealcavity.
