Manual Kneading Machine

A small laboratory batch can contain days of formulation work. The discharge therefore needs to be visible and slow enough for a technician to stop at a jar, mould or test fixture. This model uses a self-locking worm gear in place of a hydraulic tipping station, so the vessel stays at the chosen position while the sample is recovered.

The working range is up to 20 L, which keeps the movement within a practical laboratory scale. The locking action holds the vessel when the operator releases the handle, so a sample can be collected without a sudden return.

WEG motor, Guomao reducer and Siemens speed control cover mixing; NSK support and Schneider protection keep the small machine familiar to operate. SUS304 or SUS316L contact parts can be polished when clean sample changes are required.

For a laboratory machine, component choices should make the next experiment as easy to repeat as the first. The notes below link the branded hardware to drive response, sample recovery and routine inspection.

WEG Motor

The WEG motor is matched to the small batch and test-material resistance, not copied from a production-sized mixer. That keeps the drive responsive without charging the lab for unused capacity.

Guomao Gear Reducer

Guomao reducer keeps the blades in a steady test range. Mixing torque stays separate from the deliberate discharge movement, which the operator controls at the vessel.

Siemens Inverter

With a Siemens inverter, the lab can repeat a speed profile from one trial to the next. A gentle start, a holding speed and a slower final stage are available without changing the mechanical setup.

NSK Bearing

NSK bearings keep the shaft line supported when a small batch turns sticky. Alignment protects the seal area and gives the technician a consistent clearance to inspect between tests.

Schneider Electrical Components

Schneider electrical components provide a straightforward low-voltage panel for the lab. The layout stays simple, leaving the operator to focus on the formula rather than a long control sequence.

 

Applications

 

This machine suits teams that need careful sample handling and quick, clean changeovers at small scale. The examples below are common development tasks.

 

Laboratory & R&D

Formula trials, colour matching and sample preparation can be discharged at the exact point chosen by the technician. That control helps recover an expensive small batch without a sudden tilt or splash.

Chemical & Adhesive Materials

Small resin, sealant and adhesive tests often change texture quickly. A handwheel gives the operator time to observe the material and collect a representative sample.

Food Materials

A polished small chamber can support confectionery or food-base trials when the recipe and cleaning routine are compatible. The manual tilt helps the team recover the sample into a small mould or container.

Toy & Creative Materials

Colour pastes, modelling compounds and specialty craft materials benefit from visible, measured discharge. Small producers can adjust the batch without installing a full hydraulic system.

The compact configuration combines a small chamber, manual positioning and a simple control box. The operator can see the working area and discharge direction without a hydraulic cylinder beside the station.

Compact manual kneader configuration

Before fabrication, we confirm working volume, worm-gear ratio, contact finish, operator position and receiving container. The result is a small machine that fits the routine, not only the floor space.

At PDI we can check travel and holding action, shaft rotation, bearing temperature, surface finish, visible welds and the agreed electrical test. CE/EMC documentation is reference material; final records follow the ordered configuration.

The compact base is coated, fixed to a skid and packed so the handwheel and polished chamber are protected during transit. Packing photographs, a 12-month warranty and remote laboratory setup guidance are included.
