The epidemic has brought many inconveniences to people. In addition to wearing masks every day when going out, and disinfecting products such as alcohol at home, there is also nucleic acid testing! According to statistics, China's nucleic acid test exceeds 48.85 million/day, and a total of 9.214 billion nucleic acid tests have been carried out. Demand for medical plastic parts also grows. It is conceivable how much demand is for new crown antigen test kits! Therefore, the characteristics and molds of Covid-19 self test kit are introduced below.
1. Structural features
The wall thickness of the product is thin and it is not easy to fill. Covid-19 self test kit interference of the upper and lower covers directly affects the tightness of the upper and lower kits. In addition, the wall of the product is thin and long, and the overall deformation is not easy to control.
2. Material selection
ABS: The material fluidity is relatively medium, the processing temperature is relatively wide, the thermal deformation temperature is good, and it has excellent mechanical properties, its impact strength is excellent, its wear resistance is excellent, and its dimensional stability is good.
3. Mold Features
Covid-19 self test kit mould structure requirements are not high, but it is relatively difficult to control the size of the matching gap between the upper and lower covers and the matching gap between the lower cover and the reagent tablet. The mold usually mainly adopts the 1*8 layout, and the gate usually is cold runner submarine gate.
