Why Feeding Stability Matters
Keep Material Supply Clean, Continuous, and Automatic.
Feeding conveying equipment keeps resin moving from storage to the molding machine without unnecessary interruption or handling. Controlled transfer, filtration, and automatic loading help maintain material cleanliness, reduce dust, and keep each machine supplied according to production demand.
Protect Material Cleanliness
Stainless-steel contact surfaces and closed transfer reduce unnecessary exposure, residue retention and cross-contamination risk.
Control Dust Load
Dual filtration, independent filters and optional cyclone separation keep fines away from the blower and simplify cleaning.
Reduce Manual Handling
Automatic loading replaces repeated bag lifting and hand filling while supporting cleaner, scalable machine layouts.

KEY FEATURES FOR RELIABLE MATERIAL CONVEYING
Keep Material Conveying Stable, Clean, and Easy to Maintain.
Reliable conveying depends on more than just conveying capacity; it also relies on clean material-contact surfaces, effective filtration, demand monitoring, equipment protection, and easy maintenance—all of which combine to ensure the continuous and stable transport of materials.
Stainless-Steel Material Contact
Durable contact parts reduce contamination risk and simplify material changeover and cleaning.
Filtration and Dust Separation
Dual filters, reverse cleaning, independent filters and cyclone separation manage different dust loads.
Demand Sensing and Alarms
Sensor options detect material demand and provide shortage, overload or fault feedback.
Motor and Data Protection
Overload protection supports blower life while intelligent control protects settings and fault visibility.
Cleaning and Changeover Access
Hinged covers, detachable receivers and separate dust bins reduce routine maintenance time.
Engineering principleMaterial characteristics determine the architecture; consumption and distance determine the size.
Matching Materials with Production Requirements
Match the Material Loader to Material and Production Needs.
Factors such as material type, dust levels, cleanliness requirements, and equipment layout influence the material loader configuration. Select the appropriate loader based on the material’s specific characteristics and the production process’s requirements.
FEEDING CONVEYING EQUIPMENT PLANNING
Plan the Material Route Before Sizing the Equipment.
Start with the resin type and peak material demand, then verify conveying distance, receiving points, cleaning requirements, and future expansion. These factors determine the loader configuration, conveying capacity, pipeline layout, and receiver setup for the production line.
Define Material Type
Identify virgin, regrind, mixed, hygroscopic or optical-grade resin and estimate the dust load.
Calculate Consumption
Use maximum hourly resin demand, not only average production, and include simultaneous machine loading.
Measure the Route
Confirm horizontal and vertical distance, bends, hose size and the location of the material source.
Count Receiving Points
Choose direct mounting for one machine or a separated architecture for multiple receivers and shared sources.
Plan Cleaning & Growth
Consider material changes, filter access, dust-bin cleaning and whether the line may expand into central feeding.
Published Topstar Reference
Up to 700 kg/h and 10 m for configured detachable systems.
These figures do not apply to all models. Final throughput capacity must be determined by comprehensively considering resin bulk density, conveying path resistance, lifting height, hose layout, and receiving-end requirements.
From Loader to Material Network
Connect feeding with drying, mixing and machine demand.
A material feeding machine connects storage, dehumidification, metering, and conveying equipment to the injection molding machine hoppers, ensuring processed resin reaches the appropriate machines while minimizing material exposure and manual intervention.
Prepare the Resin
Dry or dehumidify hygroscopic material before it enters the conveying route.
Control the Recipe
Meter virgin resin, regrind, masterbatch and additives into the required ratio.
Move Through a Closed Route
Match the blower, filter, hose and distribution architecture to the route.
Feed Each Machine on Demand
Receiver sensing starts automatic loading only when material is required.

Feeding and Conveying Equipment FAQ
Common Questions About Feeding Conveying Equipment Selection.
Find practical answers on autoloader types, material compatibility, multi-machine feeding, hopper receiver selection, and the key production data needed to.
What does an auto loader do in injection molding?
An auto loader uses vacuum conveying to transfer plastic pellets or regrind from a bag, hopper or storage source to the injection molding machine receiver. Sensors start and stop loading according to material demand.
What is the difference between single and detachable autoloaders?
A single autoloader is a compact machine-side solution for one receiving point. A detachable autoloader separates the controller or blower from the receiver, making longer routes, higher demand and one-to-many feeding easier to configure.
Which feeder is better for regrind or dusty material?
A detachable or open-type platform with independent filtration or cyclone-assisted dust separation is generally better for regrind and dust-intensive material. Final selection must consider particle shape, fines content, bulk density and required throughput.
Can one autoloader supply multiple injection molding machines?
Yes. Topstar detachable systems can combine two or more hopper receivers for one-to-many conveying. The blower, controls, receivers and loading sequence must be sized for simultaneous demand and route resistance.
Which hopper receiver is suitable for optical materials?
The FSR optical-grade stainless-steel hopper receiver is designed for cleanliness-sensitive optical applications. Its material-contact construction and visual monitoring support cleaner handling and help reduce powder-related defects.
What data is required to select a feeding system?
Provide resin type and bulk density, hourly consumption, dust or regrind content, horizontal and vertical distance, hose route, number of machines, receiver type, cleanliness needs, material-change frequency and future expansion plans.
