HW-J500 Mixer
The HW-J500 is a fully automatic solder paste mixer from China SMT machine manufacturer HWGC. It quickly warms refrigerated solder paste, removes entrained air and mixes the paste homogeneously without opening the jar, so the material is ready for the solder paste printer as soon as the cycle ends. Two 500 g jars can be mixed at once, or one jar can be balanced by the supplied 500 g counterweight jar. Microcomputer control, an OMRON time relay, a 1,350 rpm motor, a compact 400x400x500 mm frame and 45 kg weight make it an easy addition to any SMT production line.
Key Features
- FY-series microcomputer control with a branded OMRON time relay that stops the cycle automatically at the set time
- Dual-can fixture mixes two 500 g solder paste jars at once, cutting preparation time; a 500 g counterweight jar balances single-can runs
- Sealed mixing: the jar stays closed during the cycle, so the paste is protected from oxidation and moisture absorption
- Planetary revolution plus rotation mixing warms cold paste quickly, blends it evenly and provides a defoaming effect
- Old and new solder paste can be mixed together to restore a more active, workable paste
- Balanced fixture design reduces vibration for stable, quiet operation and repeatable results
- Safety micro switch in the lower right of the cabinet stops the machine immediately when the top cover is opened
- LED digital display with a timer range of 0.01 s to 99 h 99 s across hour, minute and second units
- Standard tooling for 60-67 mm diameter jars fits common 500 g solder paste bottles; other sizes use custom fixtures

SMT Industry News
October 2026's NEPCON Asia exhibition showcased next-generation SMT placement systems, advanced packaging solutions and autonomous material handling, including the ASMPT SIPLACE V China debut, Essemtec all-in-one SMT and packaging solutions, and Hanwha Semitec chip mounters with AMR robots. As placement and material logistics get faster, solder paste preparation becomes a visible bottleneck and a source of variation before printing. A controlled mixer helps factories standardize that step: the jar stays sealed, the timer ends the cycle at a fixed point, and paste reaches the stencil at the right consistency. That repeatability supports smart factory projects that expect every workstation in an SMT production line to be predictable and documented.
Applications
The HW-J500 is used at the start of any SMT production line that prints solder paste: it warms paste taken from cold storage and delivers a ready-to-print, bubble-free material to the printer. Typical users are PCB assembly plants, EMS providers, LED and power supply manufacturers, automotive electronics suppliers, semiconductor packaging houses and R and D laboratories working with solder paste, silver paste or conductive adhesives. For small and high-mix shops, the two-jar capacity and customizable fixtures keep paste preparation quick and consistent.
