WEFILL-SYR-SF001 Semi-Automatic Adhesive Filler for 1~5,000cps Syringe Dispensing
Product Description
The WEFILL Semi-Automatic Single-Component Adhesive Filling Machine is a benchtop dispensing system that combines exceptional versatility with high precision. It is engineered to handle everything from low-viscosity, flowable fluids to high-viscosity, poor-flow pastes, while also accommodating moisture-sensitive materials and particle-filled compounds. With optional "pressurized tank feeding" and "platen supply" configurations, it enables efficient transfer from 1~200L bulk drums into syringes/cartridges. Powered by a Siemens PLC and HMI touchscreen, operators can easily input viscosity and volume parameters for automatic speed and suck-back matching, making it the ideal semi-automatic solution for batch dispensing in electronics packaging, EV battery, and adhesive manufacturing industries.
Core Positioning (WEFILL-SYR-SF001)
This standard model is specifically optimized for flowable single-component adhesives (1~5,000cps) , including UV adhesives,. epoxy resins, silicones, lubricating greases, inks, and fluxes. It features a unique "small inlet feed → pre-plunger insertion → post-filling" sequence that minimizes contamination and air entrapment, ensuring consistent fill volume and pristine material quality in every syringe. The pressurized tank supplies material continuously to a high-precision metering pump, while HMI intelligent control ensures accurate, fast, and bubble-free dispensing.
Key Features (Optimized for 1~5,000cps Fluid Adhesives)
1.Broad Material Compatibility – Fully compatible with UV glue, epoxy, silicone, grease, ink, flux, roach bait fluids, and more;
2.Universal Consumables – Fits standard dispensing syringes and medical syringes (1cc~55cc);
3.Advanced Filling Logic – Small-port inlet + pre-plunger insertion ensures air is expelled before filling, eliminating empty packs;
4.Smart Parameter Adjustment– HMI touchscreen allows direct input of viscosity and fill volume; system auto-tunes speed and suck-back values;
5.Optional Vacuum Integration– Vacuum pump module available for vacuum loading or in-line degassing to meet bubble-free requirements;
6.High Speed & Accuracy – Dosing precision maintained within ±0.5%; infinitely variable filling speed for optimized production throughput.
