| HTU -200A/B
Uses:
1. A variety of low-pressure perfusion mold
2. Temporary behalf of the mold rapid prototyping proofing
perfusion
3. Meticulous toys, parts, tooling, spare parts, works of
art, relief, wood, imitation marble, imitation copper, iron,
cast molding products, etc.
This product is a low viscosity two-liquid type, once the
characteristics of hardening can be used to injection molding.
When adding different metal additives can be used for all
kinds of plastic molds, widely used in forming components
can reduce the number of molds, improve productivity, and
cost can be reduced, is the latest generation of the mold
material.
Features:
1. High hardness 75D
2. Low viscosity
3. Prototyping rapid hardening
4. Easy color

Additive selection
|
Additives must be dry and free of water and grease.
Glass fibers, anhydrous calcium carbonate, glass beads,
silica sand, iron, copper, aluminum, and other inorganic
salt-free water can be applied. Add the total amount of
0-300% can be achieved
|
Selection of pigment
|
Dye or pigment can be added to water to achieve the
desired color, easy to process planing. |

Product Operation:
1. Perfusion using the perfusion machine:
(1) adjusting the perfusion machine out of quantity, pressure
and other conditions.
(2) If the average filler added to the main agent, hardening
agent mixing barrel vacuum.
(3) the implementation of perfusion operation.
2. No use pouring machine perfusion:
(1) After weighing, the hardener into the mixing drum, the
first lubrication bucket.
(2), after weighing, then the main agent into the mixing
bucket, mixing 20 seconds (if any filler is added 3-5 minutes
mixing the main agent, backup speed of about 100-200rpm).
(3) the implementation of perfusion operation.
Note: the main agent, hardening agent used, the need will
be covered with moisture-proof lid.
Ke Yi customers need to adjust the curing time and ejection
time.
Fast curing: 30 to 40 seconds.
From die time: 1 minute 30 seconds
Medium-speed hardening: 1 minute to 1 minute 30 seconds
From die time: 3 minutes
Slow hardening: 2 minutes 30 seconds to 4 minutes
From die time: 5 minutes
Slow hardening: 4 minutes 4 minutes 30 seconds
Time away from the mold :15-20
