● Integrated Heating & Cooling System for Precise Temperature Control
Equipped with a dual-circulation temperature control system, the mixer supports a wide adjustable temperature range with high control accuracy. This function adapts to exothermic/endothermic reactions during silicone mixing, ensuring stable material properties and consistent formula results for lab R&D and small-batch trials.
● Provide Formula Technology Support
FLEX Machinery Co., Ltd. not only supplies customers with high-quality and cost-effective silicone sealant machine line, but also offers formula technical support, such as neutral silicone sealant ,Acidic silicone sealant, Acrylic silicone sealant, etc.
● Dual-material Stainless Steel Construction & Easy Maintenance
Crafted with 304/316 stainless steel contact parts and mirror-polished inner tank, the mixer achieves a 99.9% material compatibility rate with acidic/alkaline silicone sealant raw materials. The detachable stirring paddles and tank cover allow 360° no-dead-corner cleaning, reducing cross-contamination risks and cutting maintenance time by 30% compared to conventional models.
● High-efficiency Vacuum Defoaming & Uniform Mixing
Adopting a planetary stirring structure with a rotation speed of 0–150 rpm and revolution speed of 0–800 rpm, the mixer realizes thorough mixing of high-viscosity silicone materials (up to 1,000,000 mPa·s). Its built-in vacuum system can reach a high vacuum degree, effectively removing 99% of micro-bubbles and improving the compactness of the final sealant product.
● Intelligent Frequency Conversion & User-friendly Operation
The mixer features a frequency conversion speed control system with stepless adjustment, matching different stirring speeds to diverse silicone formulas. Its touch-screen control panel enables one-click setting of temperature, speed, and vacuum parameters, with an automatic timing function (0–999 min) for standardized operation, reducing human error by 40%.
● Compact Design & Multi-functional Adaptability
With a small footprint of only 0.8 m², the mixer fits perfectly in lab environments without occupying excessive space. It integrates mixing, dispersing, homogenizing, heating, cooling, and vacuum functions in one unit, eliminating the need for multiple devices and cutting lab equipment investment costs by 25% for small and medium-sized enterprises.

● Silicone Sealant Formula R&D
Ideal for laboratory teams to test and optimize new silicone sealant formulas. The precise heating, cooling and vacuum functions ensure stable material reactions, helping R&D personnel adjust ingredient ratios efficiently and develop high-performance sealant products that meet market demands.
● Small-batch Pilot Production
Serves as a bridge between lab research and mass production. It supports small-batch trials of silicone sealants, adhesives and related high-viscosity materials, allowing manufacturers to verify process feasibility, check product consistency and identify potential production issues before scaling up.
● Academic & Research Institution Experiments
Perfect for universities and research institutions conducting polymer material studies. Its multi-functional design and compact size fit lab spaces well, enabling researchers to carry out experiments on silicone material mixing mechanisms, reaction kinetics and performance testing with high reproducibility.
● Customized Material Processing
Suitable for small and medium-sized enterprises that provide customized silicone products. It can handle various special silicone materials, such as high-temperature resistant or low-shrinkage sealants, by adjusting mixing parameters to meet the unique requirements of different clients.
● Material Loading
Open the tank cover, add pre-weighed silicone sealant raw materials into the 304/316 stainless steel mixing tank, and ensure no foreign impurities are mixed in. Close and lock the cover tightly to prepare for the next step.
● Parameter Setting
Tap the touch-screen panel to set stirring speed, temperature mode (heating/cooling) and vacuum level according to your formula requirements. Activate the timing function if needed for standardized operation.
● Mixing Process
Start the mixer and monitor the real-time operation status. The planetary stirring system and vacuum defoaming function will work simultaneously to ensure uniform, bubble-free blending of materials.
● Unloading & Cleaning
Stop the machine after mixing is completed. Release the vacuum pressure first, then open the tank cover to take out the finished product. Disassemble the stirring paddles for 360° no-dead-corner cleaning.
Q: In addition to equipment supply, does your factory provide other services?
A: FLEX Machinery Co., Ltd. not only supplies customers with high-quality and cost-effective machines, but also offers a range of services according to the customer's needs, including adhesive formula technical support, full-process production guidance, as well as overseas machine installation and commissioning services.
Q: How to maintain the stainless steel mixing tank to avoid corrosion?
A: Clean the tank with neutral detergent right after use, wipe it dry thoroughly, and avoid contact with strong acids/alkalis for long. Regularly check the mirror-polished surface for damage.
Q: Can the heating and cooling system switch automatically during operation?
A: Yes, it supports automatic temperature switching. Set target values on the touch screen, and the dual-circulation system will adjust dynamically to match your formula’s reaction needs.
Q: How to solve bubble residue problems in the final silicone product?
A: Ensure the vacuum degree reaches ≤ -0.098 MPa and extend stirring time appropriately. Check the tank cover seal for tightness to prevent air leakage during the mixing process.
Q: What should I do if the mixer fails to reach the set vacuum level?
A: First check if the tank cover is sealed tightly and if there is any air leakage at the connection ports. Clean the vacuum pump filter regularly to ensure its normal operation and avoid blockage.
Q: Is it possible to adjust the stirring speed during the mixing process?
A: Yes, the frequency conversion speed control system allows stepless speed adjustment during operation. You can modify the speed on the touch screen according to the real-time mixing state of materials.
