With the development of epoxy resin injection machine technology, the
shortcomings of traditional dipping tank are magnified because of the time
consuming and laborious manual glue mixing, the odor of open glue tank, the large
amount of waste, and the difficulty in ensuring product consistency. The existing
epoxy resin injection machine can not only realize the fixed time and fixed
quantity mold closing and constant pressure injection, but also automatically spit
out a proper amount of raw materials according to the liquid level of the glue
tank,And it already has the function of one dragging two.
It has mature applications in vacuum infusion, high pressure RTM and closed
mold infusion, and its products include high-end industries such as automotive
parts, composite hulls, wind blades, wind girder plates, etc.
The epoxy resin injection machine can realize three different working modes
according to different moulds:
Low-pressure glue injection mode: the low-pressure mold can automatically
control the discharge amount according to the pultrusion line speed, and
always maintain the injection amount of raw materials in the low-pressure glue
injection box to ensure the supply of raw materials. The pultrusion line speed
increases the equipment to automatically increase the discharge amount to
ensure the liquid level of raw materials in the glue injection box;
High-pressure glue injection mode: the high-pressure mold can ensure the
product impregnation according to the constant internal pressure of the mold, such
as the thickness and size of the product. When the pultrusion linear speed
increases, the system automatically adjusts the pressure of the glue injection box
to ensure that the product is evenly impregnated. When the pultrusion speed
decreases, the system automatically reduces the pressure of the glue injection box
to ensure that the product is impregnated to prevent leakage at the rear of the
plastic injection box.
Glue tank soaking mode: The glue tank soaking is generally used for
winding or pultrusion glue tank soaking. The system can be equipped with glue
tank liquid level control, which can automatically control the resin level to
the lowest level according to the glue tank liquid level. The system can
automatically inject glue, which can control the resin level according to the
requirements without personnel care.
