INJECTION-SIDE SCRAP GRANULATION
Plastic Granulators
Reduce suitable runners, sprues and rejected molded parts into controlled regrind for the confirmed recovery workflow.

01 / PRODUCTION TASK
Start with the scrap—not the motor size
An injection-side granulator is selected around the material, runner or part geometry, feed method, required throughput and the downstream regrind plan.
Material and contamination risk
Required throughput and operating mode
Regrind collection and reuse plan

03 / EQUIPMENT CHOICE
Granulator or shredder?
Granulators and shredders solve different size-reduction tasks.
Plastic granulator
For suitable injection molding runners, sprues and parts that fit the confirmed cutting chamber and feed arrangement.
Industrial shredder
Used for large, bulky or tough waste such as purgings and lumps before further size reduction.
04 / SELECTION INPUTS
What HWAMDA needs to match the equipment
With these inputs, HWAMDA can recommend equipment sized for your production rather than a generic model.

05 / PRODUCT CONFIGURATION
Match chamber, feed and screen to the scrap
Send photos, dimensions and material details of the runner or rejected part. HWAMDA recommends a granulator with the right cutting chamber, rotor and screen for safe feeding and consistent regrind.
06 / PRODUCTION-CELL INTEGRATION
Connect the equipment to the complete molding cell
Review capacity and interfaces across the full sequence.
- 01Molded part separation
- 02Runner / scrap feed
- 03Plastic granulator
- 04Regrind collection or loader
07 / APPLICATION REVIEW
Configure by product and production requirement
These application families can use the equipment when their material, mold and production conditions require it.
08 / BUYER QUESTIONS
Before selecting Plastic Granulators
What is a plastic granulator used for?
It reduces suitable plastic runners, sprues and rejected parts into screened regrind.
Is a plastic granulator the same as a shredder?
No. They use different size-reduction approaches and serve different feed and output requirements.
How do I select a granulator?
Provide the material, scrap geometry, maximum size, required throughput, feed method and regrind plan.
Can regrind be returned directly to production?
Only when the material, product quality rules, contamination control and process specification permit it.
