Frequently Asked Questions

Q What is an injection unit in an injection molding machine?
The injection unit is the core component responsible for melting plastic material and injecting it into the mold at high pressure. It consists of a hopper, barrel, screw, and nozzle working together to deliver precise and consistent shots of molten plastic.
Q What are the main functions of the injection unit?
The injection unit performs three primary functions: plasticizing (melting) the raw material, metering the correct shot volume, and injecting the melt into the mold cavity under controlled speed and pressure to ensure part quality.
Q How does the screw design affect injection unit performance?
The screw geometry — including its L/D ratio, compression ratio, and flight depth — directly impacts melting efficiency, mixing quality, and pressure generation. Proper screw design ensures uniform melt temperature and minimizes material degradation.
Q What materials can be processed by this injection unit?
This injection unit is designed to process a wide range of thermoplastic materials, including PP, PE, ABS, PC, POM, Nylon, and engineering-grade polymers, making it suitable for diverse industrial and consumer product applications.
Q How is injection pressure controlled in the unit?
Injection pressure is precisely controlled through the machine's hydraulic or servo-electric drive system, combined with real-time feedback from pressure sensors. Operators can set multi-stage injection profiles to optimize filling, packing, and holding phases for each specific part.
Q What maintenance is required for the injection unit?
Regular maintenance includes inspecting and cleaning the screw and barrel, checking the nozzle tip for wear, monitoring heater band performance, lubricating moving components, and verifying check ring integrity. Scheduled maintenance ensures consistent plasticizing quality and extends the service life of the unit.
