M OLD STRUCTURE:
- Gating System:
Runner: Where the molten plastic flows through before reaching different cavities.
Sprue: Where the molten plastic flows through from the injection machine to the mold.
Gate: The last opening that allows the molten plastic to flow into the cavities.
Cold Slug Well: When the molten plastic flows in the sprue and runner, it will solidify due to heat transfer with the mold. The cold slug well is where the solidified material is stored before entering the cavities.
- Guidance System:
In-mold opening/closing process, mold displacement will occur due to manufacturing tolerances and installation tolerances. When the mold is closing, it is required that the mold can return to its original position. This is where guidance and location (i.e. mold guidance system) fit in.
- Molding System:
Molding System: A closed space that consists of the core, cavity, and inserts, etc.
- Ejection System:
The ejector of the injection machine applies force on the press plate of the mold, which drives the ejector pins, ejector blocks, and lifters, etc. to push the product away from the core or the cavity and thus enable smooth mold release.
- Cooling System:
The mold itself is a large cooling system. To achieve a better cooling effect, one or more groups of cooling channels will be designed for the mold. Usually, the distance between the cooling channel and the product is twice the diameter of the channel. The coolant is not necessarily cold water – it can be water at 100 degrees Celsius depending on the mold temperature and sometimes it can also be hot oil.

M OLD MAKING IN-HOUSE:
Our Mold shop is well equipped with latest machines, such as High-speed CNC machines, EDM wire cut machines, Mirror finish capable sinker EDM machines, They are all imported from Taiwan, Switzerland, and Japan. These machines help us to ensure the molds are manufactured to the highest precision with a quality finish. Moreover, all of our processes are in-house, which allows us to accomplish short lead times, Our shop has 30 skilled toolmakers, most of whom have more than 10 years of mold making experience, they are familiar with all machining processes, the costs of each step can troubleshoot during the mold building process. Our staff is vitally important to our company, Their experience, and hard work allow Eco molding to guarantee a high-quality mold at a reasonable price.
