From Lab R&D to Production Filling: 10L Touchscreen Vacuum Planetary Mixer for Efficient Silicone Sealant Manufacturing

In silicone sealant R&D laboratories, the most persistent challenges are often uneven mixing, incomplete bubble removal, cumbersome operation, and untraceable data. A 10L touchscreen-controlled vacuum planetary mixer is engineered specifically to solve these problems—bringing precision, convenience, and reproducibility to your daily formulation work. More importantly, it seamlessly integrates with downstream filling production lines, enabling a smooth transition from lab-scale formulation to full-scale production .

Designed for Laboratory Silicone Sealant Development with Precision

Anyone experienced in silicone sealant pilot testing knows that capacity selection is a critical decision. A vessel too small for multiple sampling points; one too large increases raw material waste and cleaning burden. The 10L working volume is ideally suited for most lab-scale formula development and pre-pilot trials . A single batch supplies enough material for parallel experiments without excessive consumption, and its compact footprint (1300×800×1800mm) fits standard lab bench spaces with flexible placement and mobility.

To address the high-viscosity, deaeration-intensive nature of silicone sealants, this vacuum planetary mixer employs a dual-motion planetary system combining revolution and rotation. Revolution speed is adjustable from 0–48 rpm, and rotation speed from 0–100 rpm . A custom wall-scraping mechanism eliminates dead zones, ensuring base polymers, curing agents, and additives are thoroughly blended. The high-speed disperser shaft reaches up to 2980 rpm, effectively breaking down powder agglomerates in high-viscosity formulations . Vacuum capability (up to -0.09 MPa) enables simultaneous bubble removal during mixing—eliminating porosity defects in finished sealants and streamlining the process into a single step.

Touchscreen Control: Smarter Lab Mixing for Reproducible Results

Unlike traditional knob-and-button lab mixers, this unit features a full-touch display panel. Mixing speed, vacuum level, process time, and temperature parameters can all be set and adjusted directly on the screen, with all operational data displayed in real time—no more crouching beside the equipment with a notebook . The system supports recipe storage: once you have fine-tuned a mature silicone sealant mixing protocol, you can save it and recall it instantly for the next identical experiment. This eliminates repeated parameter adjustments, saves significant lab time, and makes data from different batches more consistent and traceable.

From Lab Mixing to Production Filling: The Complete Sealant Production Line

After formulation development and validation in the lab, the next question is how to smoothly transition to mass production. As a manufacturer with over 18 years of industry experience in mixing and filling machinery, MAXWELL provides not just standalone equipment but complete solutions covering material mixing, degassing, filling, and capping .

Mixing End: Seamless Scale-Up from Lab to Production

The 10L touchscreen planetary mixer completes lab-scale formulation development and validation, then seamlessly connects to larger capacity planetary mixers for pilot and production runs. MAXWELL's industrial planetary mixer series covers the full spectrum from lab-scale 0.5L to production-scale 2000L, meeting capacity needs at every stage . All models share the same planetary mixing principle and control logic, ensuring process parameter transferability across different equipment scales.

Material Feeding: Smooth Transfer of High-Viscosity Sealants

Transporting high-viscosity silicone sealant from the mixing vessel to the filling machine is a critical efficiency factor. MAXWELL offers a matching hydraulic press (YJ200 model) with extrusion force of 45–60 tons, compatible with standard 200L drums . The press extrudes the sealant from the drum through piping to the filling machine hopper—the entire feeding process is enclosed with no air contact, ensuring no bubbles are introduced and no material interruption, providing stable supply for downstream filling.

Filling End: High-Precision Automatic Metering Filling

For the filling stage, MAXWELL offers semi-automatic to fully automatic silicone sealant filling equipment:

• Semi-automatic filling machines: Suitable for small-batch, multi-variety production with flexible operation and quick changeover.

• Fully automatic filling lines: PLC-controlled with touchscreen operation, featuring positive displacement metering cylinders and servo motor quantitative control. Filling accuracy reaches ≤±0.5%, with speeds of 1200–2400 pieces/hour . The complete line integrates automatic bottle feeding, automatic quantitative filling, automatic capping, automatic coding, and automatic unloading—one operator can manage the entire line. After filling, an optional automatic labeling machine (compatible with round bottle and bottleneck labeling) enables full packaging automation.

Applications and Industries

This 10L touchscreen vacuum planetary mixer is not limited to silicone sealant R&D. It is equally well-suited for sealants, thermal gels, electronic silicones, solder pastes, ceramic slurries, adhesives, ointments, cosmetics, and other polymer material compounding in laboratory settings . With an optional hydraulic extrusion system, it enables integrated mixing and discharging for high-viscosity materials, reducing material loss and contamination risk during transfer.

When paired with MAXWELL's complete filling production line solutions, the system enables seamless transition from lab formulation development to production-scale manufacturing. MAXWELL's products serve customers in over 90 countries worldwide, covering chemical, electronics, new energy, daily chemical, food, and pharmaceutical industries —a reliable partner for silicone sealant and polymer material R&D and production.
