Need to crush plastic drums, hollow containers, toy shells, bottles or blow-molded plastic scrap without constant bouncing, jamming or manual pre-cutting?

The Wensui WSGT Hollow Plastic Crusher is designed for lightweight and bulky plastic products that are difficult to process with conventional plastic crushers.

With a V-type cutting system, optimized feeding structure and processing capacity of approximately 300–680 kg/h, the WSGT series helps manufacturers and recyclers reduce manual handling and improve continuous crushing efficiency.

It is suitable for processing materials such as:

· PP plastic drums;

· PE containers;

· ABS toy shells;

· blind-box plastic housings;

· blow-molded bottles;

· plastic cans and barrels;

· hollow packaging;

· rejected plastic products;

· factory plastic scrap.

For customers unsure which crusher model is suitable, Wensui can evaluate the machine configuration based on the actual material size, resin, wall thickness and required output.

Why Conventional Plastic Crushers Struggle With Hollow Products

Hollow plastics behave very differently from solid runners, lumps and small injection-molded parts.

Because they have a large volume but relatively low weight, hollow products may bounce inside the feeding hopper when contacted by the rotor.

This can cause several production problems.

Material Bouncing

The rotating knives may push lightweight products upward before establishing a stable cutting bite.

Operators often see drums, bottles or hollow toy shells repeatedly moving inside the hopper instead of entering the cutting chamber.

Low Effective Output

A crusher can have a powerful motor and still produce poor results if the rotor cannot feed the material efficiently.

For hollow plastic applications, stable material engagement often matters more than motor power alone.

Frequent Jamming

Large hollow parts can overlap near the rotor and create material bridging.

This may result in:

· unstable motor current;

· rotor overload;

· repeated shutdowns;

· manual material clearing;

· lower production efficiency.

Extra Labor for Pre-Cutting

With a general-purpose crusher, operators may need to manually cut or flatten plastic containers before feeding them into the machine.

For factories handling large volumes of scrap every day, this adds unnecessary labor and slows the recycling process.

The WSGT series is designed to address these issues at the crushing stage.

Why Choose the WSGT Hollow Plastic Crusher?

V-Type Alloy Knife System for Better Material Bite

The WSGT uses a high-strength V-type alloy knife arrangement.

Instead of applying cutting force across the full knife width at the same time, the V-shaped geometry creates a progressive cutting action.

This helps the rotor bite hollow and irregular materials more effectively.

Benefits include:

· more stable material feeding;

· reduced bouncing;

· smoother cutting load;

· improved crushing continuity;

· more consistent regrind size.

This knife configuration is particularly useful for bulky plastic products that tend to slide or move away from conventional straight knives.

Adjustable Rotating Knives

The rotating knives can be adjusted to maintain suitable cutting clearance during long-term operation.

Correct knife clearance is important because excessive clearance can increase tearing and fines, while insufficient clearance can create unnecessary mechanical load.

The knives can also be resharpened when appropriate, helping reduce long-term replacement costs.

300–680 kg/h Processing Capacity

Depending on model selection and actual material conditions, the WSGT series can provide processing capacity of approximately:

300–680 kg/h

Actual output depends on:

· material type;

· product dimensions;

· wall thickness;

· bulk density;

· screen opening;

· feeding method;

· contamination;

· required flake size.

For this reason, buyers should not select a crusher based only on catalog capacity.

Wensui recommends matching the crusher to the actual plastic product.

Reduced Need for Manual Pre-Cutting

For suitable hollow products, the WSGT can reduce the amount of cutting, flattening or breaking required before feeding.

This can help manufacturers reduce manual preparation and improve the continuity of the recycling process.

In production environments where scrap is generated continuously, removing unnecessary manual steps can have a significant impact on operating cost.

Consistent Plastic Regrind

The objective of industrial plastic crushing is not simply to make material as small as possible.

A properly configured crusher should produce a consistent regrind size suitable for downstream processes such as:

· conveying;

· washing;

· drying;

· sorting;

· blending;

· extrusion;

· pelletizing;

· in-house material reuse.

For clean and properly sorted production scrap, more consistent regrind can make subsequent recycling operations easier to control.

Five-Sided Sound-Insulated Feeding Hopper

Hollow plastic products can create considerable impact noise because they repeatedly contact the hopper before entering the rotor.

The WSGT uses a five-sided sound-insulated hopper structure with reinforced internal construction to help reduce unnecessary operating noise.

This is especially useful for crushers installed near molding or production areas.

Durable Bearing Protection

Plastic crushing generates flakes, dust and vibration.

The WSGT is designed with protected bearing structures to support long-term industrial use and reduce the risk of contaminants affecting critical components.

Routine maintenance remains important for stable crusher performance.

What Materials Can the WSGT Crusher Process?

The WSGT hollow plastic crusher can be considered for a wide range of rigid and hollow thermoplastic products.

PP Hollow Plastic

Typical applications include:

· PP drums;

· PP containers;

· toy parts;

· hollow household products;

· rejected molded products.

PE Blow-Molded Products

Suitable applications may include:

· HDPE bottles;

· PE cans;

· jerry cans;

· hollow containers;

· blow-molded industrial parts.

ABS Toy Shells and Housings

Toy manufacturers may generate ABS scrap such as:

· defective toy shells;

· collectible figure housings;

· blind-box components;

· plastic casings;

· rejected molded parts.

These materials can be crushed before further recycling or reprocessing.

PET and Other Rigid Plastic Containers

Depending on product structure and machine configuration, the WSGT can also be used for certain PET containers and other rigid hollow plastic scrap.

For unusual materials or large parts, a material test is recommended before final machine selection.

Applications

Toy Manufacturing

Toy and collectible-product factories often generate rejected shells, defective products and obsolete plastic inventory.

The WSGT helps reduce bulky plastic scrap into manageable regrind for subsequent recycling.

Blow Molding

Blow molding plants frequently need to process:

· rejected bottles;

· containers;

· drums;

· cans;

· hollow molded parts.

A crusher designed for hollow materials can reduce the feeding problems commonly seen with conventional machines.

Plastic Product Manufacturing

Factories producing large rigid or hollow plastic components can use the WSGT as part of an in-house scrap recovery system.

Plastic Recycling Plants

Recyclers can use the crusher before downstream processes including washing, sorting and pelletizing.

How to Select the Right Hollow Plastic Crusher

Choosing a crusher only by motor power is a common mistake.

For hollow plastic, the right machine should be selected according to the actual application.

Before requesting a quotation, prepare the following information.

1. Material Type

For example:

PP, PE, ABS, PET or mixed rigid plastic.

2. Maximum Product Size

Provide the largest dimensions:

Length × Width × Height

This determines whether the material can enter the feeding hopper and cutting chamber efficiently.

3. Wall Thickness

A thin PP container and a thick ABS housing require very different cutting loads.

4. Required Capacity

Specify your target throughput in:

kg/h

5. Required Regrind Size

The required final size affects screen selection and crusher output.

6. Downstream Process

Tell us whether the crushed plastic will be:

· directly reused;

· washed;

· separated;

· pelletized;

· compounded;

· sold as regrind.

This helps determine the appropriate crusher configuration.

WSGT Hollow Plastic Crusher vs. General-Purpose Plastic Crusher

The exact performance difference should always be confirmed using the customer's actual material.

Why Work With Wensui?

Selecting a plastic crusher is not only about buying a machine.

The crusher must match the actual scrap.

Wensui has decades of experience in plastic auxiliary equipment and provides crushing solutions for plastic manufacturing and recycling applications.

For each hollow-plastic crushing project, machine selection can be evaluated according to:

· resin type;

· scrap dimensions;
