|About vacuum notes type technique
It is the method of making a highly precise rubber type from
silicone rubber based on a master model, and pouring polyurethane resin and an
epoxy resin into this under a vacuum, and making a duplicate article.
In order to develop a new product, examination of a function or a design is begun, and many trial productions and tests are required.
Vacuum notes type equipment is cheap and reproduces the trial product of a plastic quickly.
A silicone rubber type manufacture process
- Powder molding - paper molding
- ABS resin molding - light molding
1. To NC Large-sized machine master model. A gate is pasted up.
2. It is mold so that master model may be surrounded.
3. Agitate the main agents and hardening agent which were measured.
4. Pour the rubber that be agitated and vacuumed into assembled mold.
5. Carry out vacuum of mold of a rubber pouring agent.
6. Carry out vacuum of the mold of rubber pouring agent.
A master is taken out from a rubber type.
The manufacture process of vacuum molding
1. Vacuum of moisture or air out from Main Agents and Hardening Agent measured
2. Combine and fix rubber type with mold
3. Set vacuumed resin in the work room.
A vacuum state is checked, and it mixes and agitates.
4. It is in Vacuum about Agitated Resin.
It pours into a rubber type.
5. Open a rubber type and take out the product.
A gate part is finished and it is completion.
