High-Efficiency 20L Double Planetary Mixer for Solder Paste & Silicone Ink

In the precision-driven electronic and electrical industry, the quality of solder paste and silicone ink directly determines the reliability of end products—from circuit board soldering to component coating. Uneven mixing can lead to poor solderability, ink delamination, and ultimately production defects. Addressing these critical pain points, the 20L double planetary mixer emerges as a high-efficiency solution, redefining mixing standards for these specialized materials.

At the heart of its performance is the advanced double planetary mixing structure, engineered to eliminate inefficiencies in traditional mixing. Two high-strength mixing paddles operate simultaneously: they revolve around the 20L stainless steel mixing chamber at 10-50rpm and rotate on their own axes at 50-300rpm. This dual-motion trajectory creates a three-dimensional mixing effect, ensuring every particle of solder paste (including flux, solder powder, and additives) and silicone ink (resin, pigments, and solvents) is uniformly dispersed. Unlike conventional mixers that leave dead zones, this design achieves a mixing uniformity rate of over 98%, significantly reducing material waste caused by uneven blending.

Efficiency is further enhanced by its optimized performance parameters, tailored specifically for the viscosity characteristics of solder paste and silicone ink. The mixer features stepless speed regulation, allowing operators to adjust the paddle speed with 1rpm precision—critical for handling low-viscosity silicone ink (1,000-5,000 cP) and high-viscosity solder paste (50,000-200,000 cP). The 20L mixing chamber is crafted from 316L stainless steel, with an inner wall polished to Ra ≤ 0.2μm. This ultra-smooth surface minimizes material adhesion, reducing residue to less than 0.5% per batch and simplifying post-mixing cleaning—a huge time-saver for batch production.

Intelligent control adds another layer of efficiency to daily operations. The mixer is equipped with a 5-inch color touchscreen that supports 8 sets of customizable mixing programs. Operators can store parameters for different solder paste formulations (e.g., Sn63/Pb37, lead-free) and silicone ink types (conductive, insulating), enabling one-click startup for consistent results. Real-time monitoring of temperature, speed, and mixing time is displayed clearly, while built-in safety features—overload protection, emergency stop, and chamber lid interlock—prevent accidents and ensure uninterrupted production.

This 20L mixer excels in versatility across electronic manufacturing scenarios. For small-batch solder paste production in circuit board factories, it shortens mixing time by 30% compared to standard mixers, boosting daily output from 15 batches to 22 batches. In electronic component coating workshops, its uniform dispersion of silicone ink ensures coating thickness variation within ±0.02mm, passing strict industry inspection standards. It also fits perfectly in R&D labs, where precise replication of mixing processes accelerates the development of new solder paste and ink formulations. Optional upgrades, such as a vacuum defoaming system and heating/cooling jacket, extend its capability to handle high-demand materials that require bubble-free or temperature-controlled mixing.

Quality and service underpin the mixer’s reliability. Core components—including the motor from Siemens and the control system from Schneider—undergo 800 hours of continuous operation testing, resulting in a failure rate below 0.3% and a service life of over 10 years. We provide comprehensive support for global clients: English and multilingual operation manuals, video-guided installation, 24/7 online technical support, and a 12-month warranty covering parts and labor. The mixer is CE, RoHS, and ISO 9001 certified, complying with safety and environmental regulations in the EU, North America, and Southeast Asia, ensuring seamless customs clearance and on-site use.

In an industry where precision and efficiency directly impact profitability, the 20L double planetary mixer stands out as a game-changer for solder paste and silicone ink processing. It combines robust performance, intelligent control, and reliable quality to drive production upgrades. Choosing this mixer means investing in consistent material quality, higher productivity, and long-term operational value.
