Covid 19 Antigen Self Test Kit Fully Automatic Production Line

In March 2022, the new crown antigen kit went online in China, and it then quickly became an important way to test for new crowns with its fast and convenient features. The surging market demand for medical supplies brings opportunities for the injection molding industry and challenges the efficiency of injection molding enterprises.

To meet the demand for efficient and stable production, XIAMEN HONGKAI SANITARY WARE CO., LTD. (hereinafter referred to as “HONGKAI”) chose Topstar injection molding automation solutions. The injection molding machine is used as the main production equipment to produce the antigen extraction tubes and test cards for the new crown antigen self-test kit.

HONGKAI is an injection molding company with more than 30 years of experience in the daily chemical and medical industries, mainly engaged in the research, development, production, and sales of plastic products such as sanitary products and medical drip tubes.   

Covid 19 Antigen Self Test Kit Fully Automatic Production Line

After using the automated production line, Mr. Wang, the general manager of Hongkai’s injection molding department, expressed great satisfaction with Topstar’s injection molding machine. “Due to the surge of orders for kits, our product delivery time is very tight, so every production step is not allowed to make mistakes.” He said, “Topstar injection molding machine not only has good stability and efficiency but also can guarantee the output. Now, one machine can produce 200,000 sets of kits every day.”

To meet HONGKAI’s production needs, Topstar customized this kits injection molding automation solution, which can realize the whole process flow of antigen extraction tubes and test cards from injection molding to taking out the material. The injection molding automation solution with Topstar injection molding machine as the core equipment, with the advantages of stability, high efficiency, short molding cycle, labor-saving, etc., to achieve a daily production capacity of 200,000 sets of a machine.   

Talking about the reason for choosing Topstar, Mr. Wang said, “First, it was recommended by friends; second, in the case of emergency at that time, Topstar was able to quickly deliver production equipment to meet production needs.” He explained, “Antigen kits such medical supplies have high requirements for plasticization quality, so when purchasing equipment, we pay particular attention to the performance of injection molding machines. We have compared other brands of injection molding machines before, but the quality of the products produced could not meet our requirements, and Topstar injection molding machines perform very well both in terms of plasticization, solubility, and efficiency and stability.”

01 Antigen Extraction Dropper

In the Antigen Self Test Kit, the antigen extraction dropper is mainly used to save the antigen extract and collect the sample from the nasopharyngeal swab. During the self-test, the user places the collected nasal swab in the sampling dropper and then squeezes the swab head by hand through the outer wall of the sampling dropper to ensure that the sample is fully eluted in the sampling dropper. Therefore, the dropper body of the antigen extraction dropper needs to meet the requirements of good plasticization quality and a smooth surface of the tube wall without burrs.

Topstar injection molding machine is equipped with a double-threaded mixing head screw, which has a strong plasticizing and mixing ability. It not only can make the material fully and evenly melt, and enhance the product quality to a greater extent, but also suitable for PE, PP, PS, AS, ABS and other materials.

At present, the demand for antigen kits is huge, on the basis of ensuring the stability of product quality, helping customers to increase efficiency and production is the key. So in the solution, Topstar upgraded the two-stage power for the injection molding machine, with 32-cavity mold, successfully helped the customer to achieve a injection molding machine daily output of 200,000 units.

02 Antigen Test Card

Large market demand and tight delivery schedules require shorter production cycles for kits. The production efficiency of antigen test cards, an important subject in the process of antigen self-testing, is particularly important.

In HONGKAI’s antigen test kit production line, the Topstar injection molding machine can produce 32 kits of top/bottom cover products at one time. 12-13s can complete the injection molding, product removal, automatic printing code (automatic fast drying), and discharging processes. The whole process does not require manual operation and is highly automated. It improves production efficiency and saves labor costs so that the enterprise can achieve high efficiency and cost reduction. With this automated production line, HONGKAI produces up to 200,000 sets of kits per day.

In addition to antigen test kit injection molding solutions, Topstar can also provide automatic assembly and sealing machine solutions for reagent kits, nucleic acid testing nasopharyngeal swab packaging solutions and other automation solutions for the medical industry. Fully support the medical industry to speed up production and provide strength to fight the epidemic.
