UPSIZING INJECTION UNITS

Increasing the capacity of an injection unit without replacing the entire unit is possible and the modification can usually be accomplished at a much lesser cost.   Upsizing involves a change in the barrel and a new screw, valve and endcap.   The capacity of the existing hydraulic system, the barrel design and resins to be processed are among the factors to be evaluated in confirming the feasibility of upsizing.  To see if your equipment could be upsized, complete the Data Requirements for Upsizing form and email or fax it to Westland.  We will analyze your information and get back to you with our recommendations.  Or, for any questions you have how, call Westland for a complete discussion of alternatives. 

DOWNSIZING INJECTION UNITS

The need to downsize an injection unit usually arises from potentially excessive residence time when attempting to produce a part with a shot size that is a small percentage of the machine's shot capacity.   Downsizing an injection unit involves a new barrel, screw, valve and endcap.   Under certain circumstances, the existing barrel may be used to meet the customer's requirements. 

Westland takes special care to insure that the new barrel has adequate yield strength to offset higher injection pressures that may result from downsizing.  If you need a smaller injection unit to process some special parts, call Westland for further assistance.  Or, complete the Data Requirements for Downsizing form and email or fax it to Westland.  We will analyze your information and get back to you with our recommendations.
