There is possibility to produce gas-assisted injection moulded  for the components that have thick walls. Applying of the gas can be reduced the mass of the product, cycle time, and the quality can be improved, aesthetical appearances, nevertheless cost reduction can be reached. Components that have thick walls also have cavity inside(handles, knobs, pedals, arms) for their manufacturing gas counter pressure is applied by the injection moulding, in which we have more than ten years old experiences and also have some skills on the areas of construction planning,toolmaking and production.
