Demark company, specialized in manufacturing PET Preform Mould injection system, consists of  technologists with rich experience, and senior engineers with master's  degree and professional in 3D. We invite many technical committee members and senior professors in mould line are as the technical consultants for our company. Various kinds of processing equipment and detection measurement instrument are imported, as well as special drawing soft is applied in designing performs, samples and manufacturing testing mold. We supply special technology training and other good after-sales service.
A. Capacity of Research and Development
Demark company has a powerful team for research and development, which is capable of manufacturing the preform molds with one cavity to ninety-six cavities including the injection system. At the same time we can manufacture preform molds especially according to customers' injection molding machine. We also design cold parts, hot runners and other main exchangeable components to fix on the imported preform molds.
B. Mould Features:
1. No cutting of valve gate is employed to reduce the labor cost.
2. Advanced hot runner system assures lower level of AA value.
3. Reasonable-designed cold water channels increase cooling effect and shorten the cycle time.

C. Material
1. The main components of preform molds are made of S136 material (Sweden ASSAB).
2. The mold base is made of imported P20.  plate method avoids corrosion efficaciously and assures long life service of the preform molds.
3. German Vacuum stove is imported for heat treatment of the components, which assures the hardness of components HRC48-HRC50.

D. Advanced processing equipment
Many machine tools are imported from USA and Japan, such as Machine center, CNC lathers, EDM and so on. All of these increases processing precision, good interchangeability and low eccentricity ≤0.10mm (preformlength≤100mm).

E. Electric heating components
1. German HOTSET heating components.
2. German intelligent temperature controller (PID continuous power controlling).
3. Offering temperature controller and voltage controller according to customers' requirement
F. Perfect inspection method.
Inspection tools include projector, hardness tester, stress tester, eccentric tester, electric balance and other inspection tools.
The screw neck is made and inspected strictly by the standard of Coca cola and the screw neck has been up to the standard of Coca cola.

G. After-sales service
 Technologists professional in after-sales line and excellent credit assures stable operation of the machines.
