Custom Pipette Tip Molds
May 22, 2023
A pipette tip belongs to a kind of plastic consumable in the field of experimental diagnosis. It is a one-time consumable that cooperates with a pipette or an automated workstation to accurately inhale a certain amount of detection reagent and release it into the corresponding detection tool. According to a different use, it can be divided into standard pipette tips, filter pipette tips, low adsorption pipette tips, automatic workstation pipette tips and wide pipette tips.
In actual application, the pipetting tip is in direct contact with the sample liquid to be tested, which will not only affect the accuracy of the pipetting results but also directly affect the analysis results if there is foreign biological contamination or dissolved substances in the pipette tip. High-quality tips need usually have the following characteristics:
1. There are no burrs and a lack of materials in the tip and mouth.
2. They have better matchiness and sealing.
3. The wall thickness is uniform; the inner wall is smooth, and there is no trace left when pipetting.
4. There is consistent pipetting accuracy.
Product characteristics and a large number of application requirements have put forward extremely high requirements on molds, molding equipment, production technology, production environment and quality control.
1. Mold making
Every process of the mold must be carefully controlled from structural design, steel selection, parts processing, and polishing to complete mold assembly. Good structural design is the prerequisite for mass production stability, and the selection of steel and the precision of parts processing are the basis for stable mass production. How to control and effectively connect the process from design, and processing, to final assembly is the difficulty of mold making. Mold making should focus on the following aspects:
Structural design, exhaust and cooling methods
The selection of steel
Precision control of mold base, mold core and parts processing
Surface polishing
2. Injection molding
The stability of mass production requires high-precision molds as the basis, and more importantly, a good production process. A good production process requires careful planning and preparation from various aspects such as production environment, machine selection, molding process, and automated production.
100,000-level purification workshop production environment
Imported high-speed electric injection molding machines
The reasonable and stable molding process
Automated manufacturing
3. Quality control
Formulating corresponding control schemes for different problems of products can ensure the pass rate of products and effectively improve the yield rate of the production process. The professionalism of inspection personnel and the use of inspection and testing equipment must be systematically trained, and the testing environment must also be strictly controlled.
Good quality control process
Constant temperature and humidity testing environment
Professional testing personnel and equipment
