5L Lab Scale Sigma Blade Mixer
Will Your Formula Behave the Same Once Real Kneading Begins?
Beaker tests can hide the problem that matters once two sigma blades begin folding a dense batch. The NH-5 creates a practical laboratory batch for observing how material responds to kneading, heating or cooling, and manual tilting discharge before a production-scale configuration is selected.

SUS304 One-Piece Cast Sigma Blades
For 10L-and-below models, HengMing uses SUS304 one-piece cast sigma blades rather than externally clad blades.

Temperature Conditions Matched to the Trial
Heating can be arranged through thermal oil, steam or an external thermal-oil circulation system, while a circulating-water jacket is available for cooling.
Manual Tilting Discharge for Small Batches
Manual tilting discharge lets the R&D team observe the process as a real working batch, not just a sample stirred in a container.
Where the NH-5 Earns Its Place
The NH-5 is built for formulation development, process verification and small-batch trials involving materials such as gum base, chewing gum, adhesives, paint-like pastes and selected chemical formulations. It is for materials that need genuine kneading action, rather than ordinary low-viscosity liquid stirring. When a formula is still being refined, this compact sigma blade mixer gives the team a more useful basis for deciding the next production configuration.

Need a Different Trial Setup?
The NH-5 is not limited to one fixed process. The standard model is designed around a 5L working batch and manual tilting discharge; the NHZ-5 adds an optional vacuum configuration when the process calls for it. Heating method, cooling jacket, contact material and electrical supply are then selected around the material, process steps and local requirements. The right laboratory mixer is not the one with the longest option list. It is the one that lets the team see the right process behavior before scaling up.
Component Choices You Can Check Before the Trial Begins
A laboratory result is easier to trust when the drive and control components are not a mystery. HengMing identifies its standard selection, including NSK bearings, WEG motors, GUOMAO reducers, and SCHNEIDER + CHINT electrical cabinet components. SIEMENS inverter control can be selected where variable speed matters. Specified brands such as ABB or SEW can also be discussed before production begins.

Questions Buyers Ask Before Choosing a 5L Sigma Mixer
Is the full 5L capacity also the working volume?
Yes. For HengMing models below 10L, the total volume and working volume are both 5L. Larger models normally use a working volume of around 700f total volume, but that reduction does not apply to the NH-5.
When is the NHZ-5 vacuum version worth considering?
NHZ-5 is the optional vacuum version of the 5L mixer. It should be considered when the material or process requires vacuum processing; the final choice depends on the actual material behavior and operating steps.
Can heating, cooling and contact material be adjusted for the process?
Yes. Heating can be arranged through thermal oil, steam or external thermal-oil circulation, while a circulating-water jacket is available for cooling. SUS304 is standard for contact parts, and the configuration can be adjusted according to process requirements and local electrical standards.
Is the NH-5 suitable for every material trial?
The NH-5 is intended for materials that need genuine kneading action, not ordinary low-viscosity liquid stirring. When material behavior is uncertain, HengMing can review the material and general process steps before recommending a trial or configuration.
How does HengMing protect the project before final payment and after delivery?
After production is completed, HengMing provides a PDI report, mixer photos and separate test videos for each function. The customer reviews and approves these records before paying the final balance, so the agreed specifications, functions and configured components can be checked against the contract before shipment. After the mixer arrives at the destination port, HengMing provides an English operation manual, electrical drawings, remote installation guidance, spare-parts support and a 12-month warranty. On-site installation can also be arranged when required.
