Product Description

2-Component Foam Machine
HT-520D 
HT-321 2-component foaming machine is a 2-component mixing and dosing system. It can be used to foam, glue and pot for various
Workpieces. HT-321 adopts Germany BARMAG high accurancy metering pump which can adapt low viscosity, medium viscosity and
High viscosity polymers and materials, Such as polyurethane, silicone, silicon gel, exposy resin and other reaction materials. HT-321
Can run with high stability as an independent equipment or a part of automatic production line. 
2-Component Foam Machine


Dosing and Mixing System

HT-321 has different operating modes. The standard control system is a movable cantilevered control panel with 15-inch touch screen. 
After adjusting the machine and prestting the parameters, the machine will run accurately, safely and efficiently according to the technical
Setting during the production. 
Control System Parameters
• Perfect combination of industrial PC and control of motion
• Real-time bus systom
• Pluggable switchpanel( aviation socket)
• 3 operating mode: Adjust/ready/automation
• Formulation management
• 3 levels password protection ((optional)
• Data backup by U disk, SI or LAN
• Accurately adjust material reaction time, feeding quantity prest, automatic cleaing and air injecting/ stirring materials by programs
• Adjust automatic material feeding by controling the pressure
• Counter and timer start automatically as the machine runs
• Monitor and digital dispaly the pressure of components
• Open interfaces
• Operating system and programs can be store in a memory card
Driver technical parameters
• Speed-control servo motor with speed and ajusting display









Raw Material-PU
PU is a product of 2-component Polyurethane. It adopts FIPFG (foamed-in-place foam gasket) technology which can foam on the
Workpiece directly. The finished product is a soft and elastic foamed gasket. This gasket is made from component A and component
B. Component A is mainly polybasic alcohol, Component B is a hardener-isocyanate. After mixing A and B according to a certain
Proportion and completely foaming, the mixture will become a soft foamed sealing strip. 





• Mixing time: Time for mixing component A and component B
• Reaction time: Time for the mixture to react( about15-60 seconds after mixing)
• Foam time: Time from reaction to finish (about 15-180 seconds)
• Dry time: Tiem for no viscosity on the suface, and no damage with touch under room temperature 25 ºC(about 2-20 minitues later)
• Available time: Time for the availability of gasket to be pressed or assembled (about 20 minitues-12 hours later)
