FAQ
Can the gravimetric blender be connected to the ERP system and MES system?
Yes, no problem. It has four protocols: TCP, UDP, ISOon TCP, and Modbus TCP. Please check which protocol your system uses.
Is it possible to automatically skip when one of the components has no materials (such as crushed materials), and continue to mix the remaining formulas and operate normally?
Okay. we can customized program. We can add a low level sensor on the ground material buffer hopper, and when ground material is lower then that sensor, it will give signal to the PLC, and PLC will skip that material. For example, your recipe is virgin 70%+ground 20%+color 2%+additive 8%, when lack of ground material, PLC will skip it, so the blender will work at virgin 70%+color 2%+additive 8%.
Do the valves operate well with ground material? Can the valves be blocked by any type of material?
Most ground materials are fine, no problem, our gravimetric blender can process them normally.
Is calibration easy to perform?
Yes, it’s easy. and we can provide operation video
Can the language of the operating system be customized?
Yes, no problem. Our standard languages
Typical Project Applications
Xiaojuren Gravimetric Blenders: Precision Dosing for Peak Performance
Empower your plastic manufacturing operations with the Gravimetric Blender, engineered for superior accuracy and unwavering stability. This advanced system expertly manages the precise dosing and mixing of diverse plastic materials, including virgin resins, additives, regrind, and color masterbatches. Its proven reliability makes it an indispensable asset across a wide spectrum of industries, from automotive and plastic packaging to home appliances, pipes, sheets, medical products, and even cutting-edge biodegradable plastics.
Gravimetric Mixer With Screw Feeder For PP, PS, and PET Crushed Materials
This gravimetric blender is specially designed for PP, PS, and PET sheet extrusion. It’s ideal for production lines that use a high percentage of crushed materials, such as trim edge regrind and thermoformed waste rolls. Unlike traditional batch blenders, which often suffer from bridging and clogging, our advanced gravimetric batch blender with screw feeding ensures smooth, consistent dosing—no material blockage, no interruptions.
Gravimetric blenders are essential in white goods production, especially for injection molding and sheet extrusion. In sheet extrusion processes, materials like ABS, PS, flexibilizers, and color masterbatch are commonly used. To ensure consistent product quality, precise dosing is critical. Our gravimetric blender, equipped with a high-sensitivity load cell, delivers accurate dosing with ±0.5% precision—perfect for multi-component blending in demanding production lines.
Gravimetric Blender With Screw Feeder For Low Color/Additive Ratio
In some extrusion formulas, the proportion of color masterbatch or additives is as low as 0.3% to 0.5%. At such low dosing rates, standard slide gate valves often fail to deliver the required accuracy. That’s why we recommend our gravimetric blender with screw feeding. The screw feeder accurately delivers small-dose additives into the weighing bin, ensuring high-precision dosing and consistent product quality.
Gravimetric Blender With Loader Unit
To save workshop space and simplify operation, we’ve integrated the gravimetric blender and vacuum loader into a single compact unit. Stainless steel pipes are used as vacuum air lines, giving the system a clean, durable, and space-efficient design.
In extrusion blow molding—such as the production of kegs, drums, jerrycans, plastic bottles, and containers—precise material dosing and mixing are critical before molding. Manual feeding often leads to inconsistent quality, material waste, and higher labor costs. Our gravimetric blenders ensure accurate, automatic dosing for consistent production and reduced waste.
