Blister Seal Tooling

Lockwood delivers the same quality you expect from our machines and blisters in our heat seal tooling for all manual and automatic machines.  We can design and manufacture heat seal tooling for new projects or duplicate existing blisters and cards using digital technology for exact replication.


No matter how complex or irregular the shape, we can design standard Blister Heat Seal Tooling or Radio Frequency Tooling (RF) Heat Seal Tooling for Lockwood, Algus or other machines.


We guarantee Lockwood blisters will feed with our tooling and machines every time!


Every complete set of tooling, which includes nesting trays, blister and card feeder chutes, heat seal plates, plug feed racks and feed plugs is tested with your product on our machines before despatch. Our goal is for you to be ready to run when your tooling arrives, we will test run as many samples as you send us.


We offer standard tooling or quick change tooling (QCT) on our automatic machines, if you opt for QCT, this will enable you to complete a full tool change within ten minutes and be running another product with minimum downtime and cost and maximum production.
