- Material conveying and centralized feeding: customized central conveying systems for enclosed transport and centralized control of raw materials.
- Automation equipment: robots, belt conveyors, automatic cutters, and associated line integration.
- Precision molding systems: the NAVIS brand for intelligent injection molding machines and all-electric precision machines.
The company describes its systems as serving customers seeking energy savings, process stability, and lower workplace contamination, which are recurring requirements in plastics manufacturing plants that run thermoplastic resins, colorants, and regrind streams.
Products and Technologies
SMANL’s product line is built around the processing stages that surround an injection molding machine, with particular emphasis on material conditioning, transport, thermal control, and recovery.
Main product categories
- Drying and dehumidifying equipment: hopper dryers and plastic dehumidifying dryers are used to remove moisture from hygroscopic plastics before molding.
- Material conveying equipment: auto loaders and central conveying systems support closed, centralized feeding and long-distance transport of resin.
- Thermal management equipment: industrial chillers and mold temperature controllers regulate process temperature in molds and auxiliary loops.
- Size reduction and recycling equipment: plastic crushers and shredders support runner, scrap, and regrind handling.
- Mixing and dosing equipment: mixers and color dose mixers support proportioning and blending of materials and masterbatch.
- Automation systems: robots, belt conveyors, and automatic cutters are positioned as part of line-level integration.
Technical features highlighted by the company
The company states that its mold temperature controllers use PID microcomputer control for accurate temperature regulation. It also describes its SWH series as suitable for proportional weighing and mixing in injection molding, with claimed precision control within ±0.2% and functions such as automatic calibration, program compensation, alarm recording, and formula storage.
The company’s centralized feeding systems are presented as enclosed and centralized, with the aim of reducing dust, noise, and heat pollution in workshops while improving consistency and efficiency. Its website also highlights a traversing servo robot suitable for plastic injection molding machines with clamping forces from 150 tons to 1300 tons, indicating that the automation range extends across a broad industrial machine size spectrum.
The NAVIS brand adds a second technical direction: high-precision intelligent injection molding machines, including cooperation with Japanese firms on all-electric precision injection molding development.
