Construction Features

Mainframe and crosshead are sturdy machined castings and cams. Pressure rolls are hardened steel for superior tool and part life. The two piece head is precision machined to ensure accurate tool alignment and guarantee the die table is precision ground and polished.

No resetting of feeder is required.

Stainless Steel Hopper

Vertical adjustment and lock provision.

Dust Removal Suction Nozzles

Positioned above and below the die table for clean operation.

Adjustable Upper Roll

This feature permits compacting of tablets at various points in the die, which extends die life. It also minimizes capping and laminating of tablets.

Handwheel Control

Press speed, fill and pressure settings.

Keywayed Upper Punch Sockets

These sockets provide punch alignment when producing
tablets of irregular shape are standard.

Pin Type Transit Level Feeder

The feeder funnels material directly over the die cavity. Stationary pins cause a cascading action that improves filling of the dies for accurate tablet weights. An adjustable gate also maintains fluidity tunnel of granulation and prevents packing in the frame.

Safety Features

Locking the lever in a disengaged position reduces the likelihood of accidental starting. All guards are interlocked to prevent access during operation.

Adjustable Spring Release

Release maintains desired pressure and helps protect tools against damage or breakage in case of accidental overload. Pneumatic release is optional.
