Injection molding
How injection Mold Design Impacts Cycle Time (Cooling Data)
For every second saved on a shot, thousands of more parts per year can be produced, which can substantially decrease the production costs.
Hot Runner vs Cold Runner injection mold : Cost & Cycle Time Data
One of the most important decisions to be made by engineers and procurement teams in modern plastic manufacturing is to choose the right runner system.
Injection Mold Tolerances: ±0.005–0.02 mm Data
What ±0.005-0.02 mm really means in injection mold tolerances, which features can hold it, and how steel, cooling and shrinkage affect the result.
