Cost-Effective Semi-Auto Potting from HY
As a cost-effective two-component potting device, HY-S55L balances flexibility and stable performance. It features 1~4 sets multi-head metering, dynamic/static mixing optional, dispensing speed 1~30g/s. Built-in observation window and automatic glue refilling avoid frequent shutdowns, with -98KPa vacuum option to eliminate microbubbles. 350kg solid frame works stably under 0~40℃ environment, AC380V standard power supply, perfect for multi-variety small-batch manufacturers with limited budgets.
Sturdy Frame & Material Selection Of HY Semi-Automatic Potting Machine For Long Service Life
Many low-cost semi-automatic glue machines adopt thin sheet metal frames and plastic guide parts, which deform after 3–6 months of frequent moving and handheld vibration, leading to unstable dispensing precision and offset glue position. HY semi-automatic potting machine uses thickened integrated cold-rolled steel cabinet with anti-rust spraying, no deformation under long-term vibration and frequent shifting. The metering pump’s glue contact parts are full stainless steel, resisting acid and corrosion from epoxy and PU glue, avoiding rust pollution to glue liquid and prolonging pump service cycle.
All electrical components adopt mainstream well-known brands to guarantee stable operation under fluctuating factory AC220V power supply. The whole machine weighs about 130kg with movable casters and adjustable foot cups, fixing position firmly during handheld potting without sliding. Independent mixing valve cabinet separates from electrical control area to prevent overflow glue corroding circuit parts. Top tri-color warning light displays real-time equipment state: green for normal operation, yellow for low glue reminder, red for failure alarm, so workers can judge machine status from a distance without checking touch screen frequently.
Customization Options
Gear, screw and plunger pumps are optional. Gear pumps suit low-viscosity transparent glue; plunger pumps handle high-filler silicone, stable flow without pressure loss for long continuous production.
Optional thin-film vacuum tank with -98Kpa negative pressure removes micro bubbles inside raw glue. Perfect for high-insulation electronic parts requiring zero-bubble potting effect.
Tank heating module for low-temperature workshops stops glue thickening and crystallization. Keep consistent dispensing speed in winter cold environment without glue waste.
15L/30L/55L stainless steel barrels optional, with built-in stirring to prevent glue sediment. Visual liquid window lets operators check glue surplus at a glance.
Extended cantilever boom with 1.5m working radius for large irregular workpieces. Free manual movement without moving products repeatedly during potting.
Optional flow & pressure real-time monitoring with auto alarm for abnormal dispensing. Effectively avoid defective products caused by pump failure or glue shortage.
Best Potting Solution for Small Batch, Multi-Product Lines
Running a production line that handles dozens of different product types in small quantities? A fully automatic potting system might be overkill — and a semi-automatic machine could be exactly what you need. The HY semi-automatic potting machine shines in high-mix, low-to-medium volume environments where flexibility matters more than raw speed. Switching between products takes just minutes — simply adjust the program settings and you’re ready to go. Handheld operation means you can pot everything from tiny sensors to large power modules on the same machine, no complex fixturing required. Unlike fully automated systems that need days of reconfiguration for new products, semi-automatic machines let you respond fast to changing orders. For factories that serve multiple customers with diverse requirements, this flexibility directly translates to faster turnaround and happier clients.


How Easy Is It to Operate a Semi-Automatic Potting Machine?
Worried that new potting equipment will require weeks of training and a dedicated technician? You can relax — the HY semi-automatic potting machine is designed to be user-friendly from day one. Most first-time operators get the hang of basic potting in under an hour, and full proficiency usually comes within a couple of days. The intuitive control panel uses simple, clear menus with numeric inputs, no complex programming required. Changing glue ratios, adjusting dispensing volume, or switching between saved programs takes just a few button presses. The handheld dispensing gun is lightweight and ergonomic, so operators can work comfortably for full shifts without fatigue. Anti-curing and self-cleaning functions handle most maintenance automatically, meaning your team spends more time producing and less time troubleshooting. For factories without specialized technical staff, this ease of use is a game-changer.
Improve Potting Quality Consistency with Semi-Automatic Machines
If you’ve ever had batches of potting products fail quality checks because of inconsistent mixing ratios or uneven glue distribution, you know how costly quality issues can be. The HY semi-automatic potting machine eliminates the biggest variable in manual potting — human error. With precision metering pumps delivering ±2% mixing accuracy every single time, you get the same glue ratio, same volume, same cure performance across every single unit. No more under-filled parts, no more weak bonds from off-ratio mixing, no more rework because one operator poured differently than another. The result? Your pass rate goes up, your rework costs go down, and your customers get products they can actually rely on. Many factories see their first-pass yield jump from 85-90% to over 98% after switching to semi-automatic potting. When quality is your reputation, consistency is everything.


Save Factory Space with Compact Semi-Automatic Potting
Factory floor space is expensive, and every square meter counts — especially if you’re running a growing operation in a limited area. That’s where the HY semi-automatic potting machine really stands out. Unlike fully automatic in-line systems that can take up 5+ square meters of dedicated space, this compact machine fits neatly into a corner or existing work cell with minimal footprint. Most models occupy less than 2 square meters total — about the size of a standard workbench. The machine can even be mounted on casters for easy mobility between production areas when needed. No need to rearrange your entire production line or build out extra space just to add potting capability. For workshops that are already tight on space, or for companies looking to add potting capacity without major facility changes, semi-automatic machines offer a practical, space-efficient solution that delivers real results without the real estate headache.
Fields of Application


- Small Batch LED Driver Production
Fit for small LED factories with multiple power driver models. Hand-held gun flexible potting adapts small-batch mixed production. Adjustable dispensing speed matches tiny bulb drivers and large flood light modules, auto cleaning reduces daily manual disassembly work greatly.
- Auto Small Electronic Sensors
Used for pressure, temperature and reversing sensors with high-viscosity silicone glue. Optional plunger pump ensures stable mixing ratio after long-hour manual operation, vacuum defoaming improves vibration and temperature resistance of vehicle-grade parts.
- Household Appliance Control Boards
Suitable for air conditioner, water heater and washing machine small circuit boards. Foot switch frees both hands to place workpieces, one operator can handle 2–3 sets of equipment to cut labor cost significantly.
