What is a rjg Master Molder?
The Master Molder® I qualification is designed for the Process Technician, Engineer, or Manager who needs to understand and demonstrate injection molding skills at the machine. This hands-on, in-depth training enables participants to leave with solid skills that can be applied immediately in their facility.
Who is a master molder?
Master Molders have completed rigorous, certified training programs in scientific plastic injection molding. They’re able to identify and apply methods, strategies & techniques that not only solve the issue, but also create parts with the highest cost-to-quality outcome.
What is Rjg eDART?
The eDART® System is the most comprehensive and powerful process monitoring and control system for plastic injection molding applications. It helps you gain control over the two greatest variables in injection molding: people and plastic.
What is decoupled molding?
The concept of DECOUPLED MOLDING(SM) is simply separating the molding process to specific fill, pack and hold portions of the process. A Decoupled II process suggests filling to position, then joins the packing and holding phases together, utilizing second stage pressure to pack out the mold and hold until gate seal.
What is intensification ratio in injection molding?
The machine intensification ratio, or the material/hydraulic pressure ratio is the direct relationship between the injection pressure and the hydraulic pressure. This is the ratio of the resin pressure in front of the screw, compared to the oil pressure in the piston of the injection molding machine.
What is scientific molding?
Scientific molding is a systematic approach to injection molding that is based largely on the tenets of the scientific method (developing and testing a hypothesis, drawing conclusions, and providing reproducible results).
How do you calculate intensification ratio?
Refer to the machine manual to find the machine intensification ratio. A typical ratio is 10, and the typical range of the ratio is between 7 and 15. To calculate the machine intensification ratio, divide the piston area (A h) by the screw area (A m), as shown in the following diagram.
What is intensifier ratio?
The intensification ratio is equal to the ratio of the effective areas of the hydraulic ram to that of the screw check valve.
How do I choose an injection Moulding machine?
How do I choose an injection molding machine?
- Mold size (width, height, thickness), weight and special design.
- Type and quantity of plastic materials to be used (single or multiple materials).
- The outer dimensions of the products (length, width, height and thickness) and their weight.
What is maximum daylight in injection Moulding machine?
Maximum daylight is the maximum gap allowed between the two plates, whereas; the minimum gap is the minimum permitted daylight. Example: According to the machine specification, the maximum mold height is 790 mm, and the minimum mold permitted height is 300 mm.
