AB Two-Component Adhesive Filling Machine for High-Viscosity 1:1 50 ml & 400 ml Cartridges with Press-plate feeding

A: The WEFILL-CAR-AB-F005-400-50 is designed for high-viscosity paste adhesives with a viscosity range of 10,000 to 1,000,000 cps, including epoxy resins, two-component polyurethane (PU) adhesives, acrylics (MMA), silicone sealants, structural adhesives, stone panel adhesives, rebar anchoring adhesives, and more. It is compatible with major brands such as 3M, Henkel (LOCTITE), Huntsman, H.B. Fuller, and Permabond. While the standard configuration is 1:1 ratio for 50ml and 400ml cartridges, the machine supports custom ratios from 1:1 to 20:1 (commonly 2:1, 3:1, 4:1, 5:1, 10:1) and custom filling volumes from 10ml to 1500ml (e.g., 12ml, 24ml, 200ml, 250ml, 490ml, 600ml, 1000ml). Simply contact us with your specific material and packaging requirements.

A: The machine delivers a filling accuracy of ±1% with a servo-driven pump system that ensures consistent ratio accuracy and bubble-free filling. Production speed is 480–600 pcs/hour for 50ml (1:1) and 180–300 pcs/hour for 400ml (1:1). To prevent dripping and stringing, the dual-action suction dispensing head is equipped with multiple seals that create a vacuum back-suction effect after dispensing stops (note: for high-viscosity materials, some stringing may still occur and is considered normal). The precision gear metering pumps and servo motor drive system work together to maintain stable material flow and precise shot sizes.

A: Operation is intuitive via a Siemens 7-inch capacitive touchscreen HMI with Siemens PLC control, allowing tool-free adjustment of fill volume, ratio, and speed; a foot-operated switch and manual/semi-automatic mode selector add flexibility. For batch changes, the rear-mounted automatic lifting device enables independent loading and unloading of 50ml and 400ml cartridges, drastically reducing downtime. Material feeding uses a 20L (5-gallon) press-plate system that accommodates standard pails directly, minimizing transfer steps and contamination risks. Customization options include: constant temperature heating for temperature-sensitive adhesives, 200L (55-gallon) large platen supply for high-volume production, SUS316 stainless steel contact parts for corrosion resistance, ATEX explosion-proof configuration for hazardous environments, and custom ratios/volumes as noted above. The machine requires 220V/1-phase/50Hz (customizable) and 0.4–0.7 MPa air pressure, and measures L1400 × W1200 × H1800 mm at 450 kg, with swivel casters for mobility.

A: Optional configurations include:

1.Constant temperature heating system for temperature-sensitive adhesives

2.Customized mixing ratio and filling capacity (1:1 to 20:1; 10ml–1500ml)

3.200L (55-gallon) large platen supply system for high-volume production

4.SUS316 stainless steel contact parts for enhanced corrosion resistance

5.ATEX explosion-proof system upgrade for hazardous production environments

A: Cleaning focuses on the mixed/dispensing parts, because Component A and Component B remain completely isolated inside the machine (pails, pumps, pipelines) and only contact each other at the mixing tube, where curing occurs.

For daily shutdown (same adhesive, short downtime): Detach the mixing tube (or dispensing head) from the front of the machine, immerse it in industrial alcohol or a dedicated cleaning solvent, and clean thoroughly. Then wipe the dispensing head outlet with a soft cloth dipped in solvent. No other parts need cleaning as long as the mixing tube is kept clean.

For changing adhesives or long-term shutdown (more than several days): A thorough cleaning of the entire material path is required: (1) Drain residual adhesive from the A/B pails or 20L platen; (2) Add cleaning solvent (commonly industrial alcohol or acetone, depending on your adhesive) into the A and B paths separately and circulate it through each pipeline, metering pump, and valve using manual mode until the discharged liquid runs clear; (3) Blow dry the A/B pipelines with clean compressed air to expel residual solvent; (4) Wipe residual adhesive from the 20L platen and pail interiors to prevent hardened lumps from entering the pump.

Key precautions: Industrial alcohol is the most common and economical solvent; acetone can be used if alcohol is ineffective, but confirm seal compatibility first. Always wear solvent-resistant gloves, keep the workshop well ventilated, and strictly prohibit smoking or open flames. Since the product page does not provide a specific cleaning guide, the safest approach is to contact WEFILLTEC for an official cleaning manual (info@wefilltec.com) or ask for the solvent recommended for your specific adhesive — tell them your adhesive type (e.g., epoxy, PU, acrylic) and cleaning scenario (daily shutdown, weekend stop, or adhesive change) to get targeted advice.
