What types of toolings are used in thermoforming?
Machined Aluminum Molds – are usually done on CNC machines from generated CAD files and can be either male or female. They hold very close tolerances and can be mounted on temperature control bases and used with or without plug assist molds. Cast Aluminum Molds – are usually used for parts with large draw ratios and can be either male of female. They are cast at a foundry from a pattern machined or built by Helmy from wood and composite material. They can also be mounted on temperature control bases and used with or without plug assist molds. Temporary Molds – are usually made for prototyping and short production runs. These molds are usually made from wood or composite material and are cost efficient. They normally produce prototype parts that are used to judge fit, form and functions and to establish the required R&D before going to final productions. What is the typical lead time for a project? Helmy prides itself on doing everything in-house therefore providing customers with effic
