INJECTION-SIDE SCRAP GRANULATION

Plastic Granulators

Reduce suitable runners, sprues and rejected molded parts into controlled regrind for the confirmed recovery workflow.

Plastic granulator for injection molding runners and sprues
Configuration is confirmed against the actual production duty.

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.

01

Runner, sprue or rejected-part dimensions

02

Material and contamination risk

03

Required throughput and operating mode

04

Regrind collection and reuse plan

02 / OPERATING RELATIONSHIP

How the equipment fits the process

The flow below shows the functional relationship used for project review. Final piping, controls and connections follow the confirmed equipment.

  2. 02Controlled feed
  3. 03Cutting chamber
  4. 04Screened regrind
  5. 05Collection / approved reuse

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.

  4. 04Regrind collection or loader

Return suitable regrind to material handling

If approved by the product and material process, the regrind route may connect to a loader or controlled blending step.

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.
