01 / DEMAND
Machine consumption
Shot weight and cycle time establish how much resin each machine needs.
Feeding and Conveying System
A feeding and conveying system transfers plastic pellets from material sources to receiving hoppers at injection molding machines. It connects material pickup, conveying lines and receivers into a coordinated supply arrangement for the production area.
Topstar’s feeding and conveying system can be configured for one-to-multiple material supply. For a central feeding system project, the arrangement should be matched to resin types, machine consumption and the installed conveying route.
Features
- 1. The main controllers and material hopper receivers are designed separately.
- 2. Can match 2 or above 2 hopper receivers to achieve one to multi combination conveying.
- 3. Material conveying capacities can be up to 700kgs/hr.
- 4. The maximum loading distance can be 10m, suitable for conveying materials over long distance.
Material Supply Applications
- 1. Multiple Injection Molding Machines
One-to-multiple feeding for machines using the same resin, with replenishment matched to each machine’s demand.
- 2. Centralized Material Sources
Material transfer from designated storage or pickup locations to receiving points across the production area.
- 3. Separate Resin or Color Groups
Defined supply paths for machines processing different resin grades or colors.
- 4. Workshop Feeding Upgrades
Configuration review for workshops moving from manual material loading to automatic conveying.
Typical production areas include plastic packaging, electronics and appliance components, and automotive plastic parts.
Adequate supply of goods, available for delivery within 35 days.
Material distribution
One feeding system.
Clearly assigned material paths.
A feeding and conveying system connects resin sources to the machines that use them. Plan supply groups around resin grades, colors and machine demand.
A central feeding system can share vacuum resources while keeping different material routes separate.

Multi-machine supply
Keep replenishment aligned
with production.
A one-to-multiple conveying system must balance machine consumption with the time available for each refill.
02 / BUFFER
Material at the machine
Usable hopper capacity determines how long production can continue between refills.
03 / REPLENISHMENT
Loading sequence
Shared conveying equipment must serve each receiving point within its available loading window.

Conveying capacity depends on the complete route—not floor distance alone.
Route & capacity
Size the system for
the actual material route.
A plastic material conveying system needs to account for pipe length, lift, bends and resin characteristics together.
- Critical receiving points: assess refill time alongside material demand.
- Long-distance resin conveying: confirm delivery rate for the proposed material and layout.
Material changeover
Correct resin.
Correct destination.
An injection molding feeding system should make material identity clear from the source to the machine. Dedicated and shared paths need different changeover controls.
01
Identify the source
Confirm the resin grade, color and assigned supply route.
02
Clear shared paths
Check residual material in connections, lines and receivers before switching.
03
Verify the destination
Confirm the receiving machine before restarting material supply.
Processing optical-grade materials?
An optical grade material conveying system requires cleanliness checks across the full route, not only the receiver. Define acceptable carryover and inspection criteria for the application.
