In plastic processing plants, material cost, labor cost, and workshop management all have a direct impact on production profit. This is especially true in injection molding and blow molding operations, where sprues, runners, edge trims, and small defective parts are generated every day.

If these materials are not handled properly, they can quickly take up valuable floor space, increase manual handling, and add extra recycling costs. However, these plastic scraps are not simply waste. When they are collected and granulated in time, they can often be reused in production at a proper ratio.

The WSGI beside-the-press granulator is designed for this exact purpose. It allows plastic processors to recycle production scrap directly beside the molding machine, helping factories reduce waste and improve material utilization.

Designed for Injection and Blow Molding Scrap Recycling

The WSGI beside-the-press granulator is suitable for processing sprues, runners, edge trims, small rejected parts, and lightweight plastic scraps generated during injection molding and blow molding.

Instead of sending these materials to a centralized crushing area, the granulator can be placed next to the molding machine. This makes it possible to recycle scrap immediately after it is produced.

This machine-side recycling method helps reduce material transportation, manual handling, and temporary scrap storage. For workshops with multiple molding machines and continuous production, beside-the-press recycling can make the production area cleaner, more organized, and more efficient.

Side-Drive Structure for Stable Operation

The WSGI granulator uses a side-drive structure to power the cutting system. Compared with some traditional transmission designs, the side-drive layout offers advantages in machine stability, equipment layout, and maintenance access.

A stable drive system helps the cutting chamber operate more consistently during granulation. It also reduces the risk of material jamming, abnormal wear, and unexpected downtime.

For plastic processing workshops that require long operating hours, machine stability is not only about productivity. It also affects maintenance cost, labor workload, and the overall efficiency of the recycling process.

Medium-Speed Granulation for Balanced Performance

In beside-the-press recycling, the quality of the granulated material is important. If the regrind size is uneven, it may affect feeding stability and later molding performance.

The WSGI beside-the-press granulator adopts a medium-speed cutting design. This structure provides a practical balance between granulation efficiency, noise control, and particle uniformity.

The recycled material is more consistent in size, making it easier to mix with virgin material at a suitable ratio. This helps reduce raw material waste and supports more stable reuse in production.

Side-Feed Design to Reduce Jamming

Smooth feeding is one of the key factors that determine whether a beside-the-press granulator is easy to use.

The WSGI granulator features a side-feed design, allowing sprues, runners, and small plastic scraps to enter the cutting chamber more smoothly. This helps reduce material blockage, frequent cleaning, and unnecessary production interruptions.

For operators, easier feeding means less manual adjustment. For factory owners, it means less downtime, lower labor involvement, and more stable production flow.

Compact Structure for Modern Workshops

The WSGI beside-the-press granulator is also designed with workshop space and operator convenience in mind.

Its overall height is reduced, making feeding easier for operators. In many applications, no additional feeding tool or auxiliary platform is required.

The machine body is also more compact than traditional designs, helping save approximately 25% of floor space. This is especially useful for injection molding workshops where machines are closely arranged and space is limited.

In addition, the simplified structure makes daily cleaning, blade inspection, and basic maintenance more convenient. Minor issues can often be handled faster, helping reduce maintenance downtime and service costs.

Lower Total Cost for Plastic Scrap Recycling

The cost of plastic scrap recycling is not limited to the granulation process itself. It also includes material handling, storage, labor, energy consumption, maintenance, and raw material loss.

By recycling scrap directly beside the molding machine, the WSGI beside-the-press granulator helps reduce secondary handling and centralized processing pressure. The granulated material can then be reused according to production requirements, helping factories reduce the consumption of virgin resin.

With low noise, controlled power consumption, and stable operation, the machine is suitable for long-term use in production environments. For factories that generate sprues, runners, or small defective parts every day, this type of machine-side recycling equipment can become an important part of material cost control.

Suitable Applications

The WSGI beside-the-press granulator is suitable for:

1. Injection molding factories with regular sprue and runner waste

2. Blow molding workshops with edge trims and small rejected parts

3. Plastic products manufacturers looking to reduce material waste

4. Production plants that want to reduce scrap storage and handling

5. Workshops with limited floor space

6. Factories that require cleaner, quieter, and more efficient recycling solutions

Conclusion

For plastic processing companies, reducing production cost is not only about buying cheaper raw materials. It is also about improving material utilization and managing production waste more efficiently.

The WSGI beside-the-press granulator helps recycle sprues, runners, small defective parts, and plastic scraps directly beside the molding machine. Its side-drive system, medium-speed granulation design, side-feed structure, and compact body make it well suited for continuous machine-side recycling.

For workshops that generate plastic scrap every day, beside-the-press granulation can be a more efficient alternative to centralized collection and delayed recycling. With the right granulator, plastic waste can be turned back into usable material, helping manufacturers achieve cleaner production and lower operating costs.

FAQ

What is a beside-the-press granulator?

A beside-the-press granulator is a compact plastic recycling machine placed next to an injection molding machine, blow molding machine, or other plastic processing equipment. It is used to granulate sprues, runners, edge trims, and small defective plastic parts directly at the production site.

What materials can the WSGI beside-the-press granulator process?

It can process plastic sprues, runners, small rejected parts, edge trims, and lightweight production scraps from injection molding and blow molding processes. The exact application depends on the plastic material, part size, hardness, and recycling requirements.

What is the difference between a beside-the-press granulator and a central granulator?

A beside-the-press granulator is compact and designed for immediate recycling beside the production machine. A central granulator is usually larger and used for processing larger quantities of plastic waste in a separate recycling area.

Can the granulated plastic be reused directly?

In many cases, clean and uncontaminated plastic scrap from the same material can be mixed with virgin resin at a proper ratio. The recommended ratio depends on the material type, product requirements, and molding process.

How does a beside-the-press granulator help reduce costs?

It reduces scrap handling, storage space, transportation, labor involvement, and virgin material consumption. By recycling scrap immediately, factories can improve material utilization and reduce overall production waste.
