Products and Technologies

Loss-in-weight feeders

Loss-in-weight feeders measure the reduction in the weight of a material-holding hopper over time and use that measurement to regulate the feed rate. The control system compares actual material loss with the target rate and adjusts the feeder motor accordingly.

This method is particularly suitable for applications requiring accurate formulation, including:

Polymer compounding.
Masterbatch production.
Filled and reinforced plastics.
Powder and additive dosing.
Continuous extrusion.
Chemical and specialty-material processing.

The supplier’s listed range includes liquid weighing loss-in-weight feeders and equipment for powder and pellet materials.

Single-screw and twin-screw feeders

Single-screw feeders are commonly used for free-flowing pellets, granules, and certain powders. Twin-screw feeders can offer improved handling of cohesive, difficult-flowing, or bridging-prone materials because the intermeshing screw geometry promotes controlled material movement.

Typical technical variables include:

Screw diameter and length.
Screw geometry and pitch.
Hopper capacity.
Motor speed and control range.
Material bulk density.
Target feed rate.
Residence time and discharge characteristics.

The company lists both double-screw and single-screw loss-in-weight feeding machines, indicating a product strategy that addresses different flow behaviors and dosing requirements.

Digital-controlled feeders

Digitally controlled feeders use electronic instrumentation and programmable control systems to maintain a specified material-delivery rate. Depending on system design, such equipment may incorporate load cells, variable-frequency drives, servo motors, touchscreen interfaces, alarms, and communication functions for integration with broader production-control systems.

Digital control is valuable where processors need repeatable recipes, rapid adjustment of set points, and monitoring of material consumption. It also supports the move toward more automated extrusion and compounding lines.

Liquid feeding equipment

Liquid feeders are used for oils, plasticizers, liquid additives, and other process fluids. Their design must account for viscosity, temperature, pulsation, pump characteristics, and chemical compatibility between the wetted parts and the conveyed material.

In plastics compounding, liquid dosing may be combined with solid feeding to create a controlled formulation. Stable liquid delivery is therefore relevant to the production of filled compounds, modified polymers, and specialty materials.

Applications and End Markets

Changzhou Kangze’s equipment is associated primarily with plastics and polymer-processing applications. Relevant end markets include:

Plastic compounding and masterbatch production.
Extrusion of profiles, sheets, films, pipes, and technical products.
Production of filled or mineral-reinforced compounds.
Recycling and reprocessing of polymer materials.
Manufacture of polymer blends and additive-containing formulations.
Chemical and materials-processing operations requiring controlled dosing.

Feeding machinery is also used outside plastics where powders, granules, or liquids must be introduced at controlled rates. Its technical relevance depends on the material’s flowability, bulk-density variation, moisture sensitivity, particle size, and tendency to segregate.

Global Presence and Market Position

Changzhou Kangze is located in Changzhou, an important manufacturing center in Jiangsu with established plastics, machinery, chemical, and equipment-production industries. Its presence on international supplier platforms and plastics-industry marketplaces supports access to overseas buyers and distributors.

The company competes in a specialized equipment segment that includes Chinese machinery suppliers and international manufacturers of gravimetric feeders, volumetric feeders, dosing systems, and extrusion auxiliaries. Competitive factors in this segment commonly include:

Dosing accuracy and repeatability.
Stability across changing bulk densities.
Compatibility with powders, pellets, liquids, and recycled materials.
Ease of cleaning and material changeover.
Control-system integration.
Equipment customization.
Installation, commissioning, and after-sales support.
Total cost of ownership.

No verified market-share figure is established here. The company’s publicly listed product range indicates a specialized position in feeding machinery rather than a broad portfolio spanning the entire plastics-machinery value chain.

Research and Development

Research and development in feeding technology generally focuses on improving measurement, control, material handling, and integration with production lines. For a supplier such as Changzhou Kangze, technically significant development areas include:

Improved load-cell measurement and signal stability.
More responsive motor and screw-speed control.
Better handling of cohesive powders and low-bulk-density materials.
Reduced pulsation in liquid dosing.
Faster recipe changes and calibration.
Compatibility with centralized line-control systems.
Design adaptations for recycled and variable-quality feedstocks.

The growing use of recycled polymers creates particular engineering challenges. Recycled materials may vary in particle size, shape, bulk density, moisture content, and contamination level. Feeding equipment must therefore maintain stable delivery despite greater variation than is typical with uniform virgin pellets.

Sustainability and Environmental Considerations

Feeding systems contribute indirectly to sustainability by supporting accurate material dosing and reducing formulation errors, overfeeding, and off-specification production. Precise control can improve material utilization and help processors incorporate additives, fillers, and recycled polymers at controlled proportions.

The equipment itself also participates in several broader environmental trends:

Increased use of post-industrial and post-consumer recycled polymers.
Greater demand for lightweight and resource-efficient products.
Development of compounds containing recycled or mineral-based constituents.
Efforts to reduce production scrap and unnecessary material loss.
More efficient monitoring of raw-material consumption.

These benefits depend on system calibration, operator practice, material preparation, and the overall design of the processing line. Feeding equipment alone does not determine the environmental performance of a plastics product.

Quality Management and Certifications

Supplier information lists ISO 9001 as the company’s management-system certification. ISO 9001 provides a framework for quality-management processes, including documentation, customer requirements, process control, corrective action, and continual improvement.

For feeding equipment, quality assurance commonly involves verification of:

Load-cell and weighing-system performance.
Motor and drive operation.
Screw and hopper dimensions.
Material-contact surfaces.
Control-panel functionality.
Feed-rate stability.
Safety and electrical-system conformity.

The practical value of certification depends on implementation across design, sourcing, assembly, testing, installation, and service activities.

Innovations and Future Outlook

The future market for feeding equipment is likely to be shaped by the increasing complexity of polymer formulations and the need for more flexible manufacturing. Important development directions include:

Higher-resolution gravimetric control.
Automated calibration and condition monitoring.
Digital production records and material-consumption analytics.
Remote diagnostics and connected machinery.
Modular feeder designs for rapid product changeover.
Improved dosing of recycled, fluffy, cohesive, or irregular materials.
Lower-energy drive systems.
Greater integration with extrusion, compounding, and factory-management controls.

Changzhou Kangze’s existing emphasis on loss-in-weight, digitally controlled, liquid, single-screw, and twin-screw feeders provides a foundation for participation in these developments. Its longer-term market position will depend on technical reliability, customization capability, international service support, compliance with destination-market requirements, and the ability to address difficult-to-feed recycled and specialty materials.
