Polymers Batch Injection
Hard polymer chip batch injection molding/bonding
Injection molding refers to a method of obtaining a molded article by agitating a fully melted plastic material with a screw at a certain temperature, injecting it into a mold cavity with a high pressure, and solidifying it by cooling. This method is suitable for mass production of complex shaped parts and is one of the important processing methods. There are six stages: mold clamping, injection molding, pressure keeping, cooling, mold opening, and product removal. The injection molding of the microfluidic chip has strong product consistency, higher efficiency, and is more suitable for mass production, and has attracted more and more attention.
Mold design: Wenxi shares can carry out pre-assessment of all-round mold injection according to the requirements of customers, and can put forward their own rationalization suggestions. Precision Molding: In the mold verification stage, we can help customers solve the problems encountered in the microfluidic chip during trial production and formulate solutions. Through professional design, the microchannels formed by precision molding can achieve small size deviations, high precision and consistency. Strong features. Chip seal: It can provide a variety of sealing methods for perfect sealing and high success rate at one time.
