Zinc Shot is a very common Metal Abrasive used on Aluminium die casting parts and Zinc die casting parts. Zinc shot has a similar density but lower hardness. It could clean the surface of some soft casting parts without any damage while steel shot can not. Compared with aluminium, it is heavier and safer when shot blasting. Benefit from these advantages, Zinc shot is widely used in metal casting industry for surface treatment.
Longlived Zinc Shot is made from high qiality zinc wire by drawing, cutting and rounding. There are five shapes of Longlived Zinc Shot and they are as cut, G1, G2, G3 and even G4. The size is from 0.25mm-3.0mm. Of course, customize is available according to your requirement.
Longlived metal abrasive make your shot blasting cheaper, faster and cleaner.

The selection of pressure gauges should be based on specific requirements and specific analysis. In accordance with the technical conditions proposed in the production process, in accordance with the principle of conservation, a reasonable choice of type, model, range, accuracy level. The choice mainly considers three aspects:
How to choose a suitable pressure gauge
In simple terms, in order to prevent damage to the instrument, the maximum pressure measured by the pressure gauge cannot exceed 2/3 of the upper limit of the instrument. In order to ensure the accuracy of the measurement, the measured pressure cannot be lower than 1/3 of the upper limit of the scale. . When the measured pressure fluctuation is relatively large, the pressure variation range should be 1/3 to 1/2 of the upper limit of the scale.
(1) Determine the range of the instrument according to the size of the measured pressure. Elastic pressure gauges, in order to ensure that the elastic elements can work reliably in the safe range of elastic deformation, when selecting the range of pressure gauges, it must be taken into account that there is enough room left, usually when the measured pressure is relatively stable. Below, the maximum pressure value should not exceed 3/4 of the full scale; under the condition that the measured pressure fluctuation is relatively large, the maximum pressure value should not exceed 2/3 of the full scale. In order to ensure the accuracy and accuracy of the measurement, the measured pressure value should not be less than 1/3 of the full scale.
(2) The accuracy of the meter is determined based on the maximum measurement error allowed for production. When selecting, the pressure meter with low precision and low cost should be used as far as possible to meet the production requirements.
(3) The nature of the medium to be measured should be considered when selecting. Such as the level of temperature, viscosity, corrosion, degree of contamination, inflammable and explosive. Also consider the on-site environmental conditions such as high temperature, corrosion, moisture, vibration, etc. In order to determine the type, model, etc. of the pressure gauge.
