We invent, design, develop, build, and sell specialized equipment for manufacturing, mostly for the medical catheter / balloon / stent industry. We strive to understand the relationships between product, process, and equipment, so that we can make the most capable equipment and help our customers to achieve highest quality and lowest cost manufacturing processes.

We use complexity sparingly in our designs, where we can see that it will improve your quality or productivity. Our simple designs, however, are born of sophisticated engineering analysis and mathematical models. Blockwise Engineering LLC is an Arizona company, formed in the year 2000. Blockwise equipment is profitably making medical devices at over 400 companies worldwide.

Our customers include ALL of the world's large balloon catheter, stent, and heart valve manufacturers, many medium-sized and small manufacturers, and also many universities and regulatory agencies. Our lean and fast 24-person team is located at our factory in Tempe, Arizona.

Blockwise is an industry leader in balloon wrapping (balloon folding) equipment.
These machines pleat a balloon to form a number of "wings", and wrap the wings around the catheter shaft.
The pleating station divides the balloon into a number of wings spiraled around the central shaft.
The pleating and compression dies are temperature-controlled.
The differences between the models VE, VC, and VS are not in process quality, but rather in convenience, productivity, and mistake-proofing.
Blockwise balloon wrappers (balloon folders) have heated dies, and the VE and VC machines feature full process control with recipes.
A full-featured balloon wrapping (aka folding) machine with electric actuation, for pleating and compressing catheter balloons.
Our most productive balloon wrapping machine pairs a high-performance microcontroller with a touchscreen HMI to provide intuitive and flexible control of the balloon wrapping process.
All process settings are under software recipe control.
Pleating and compression stations are both actuated by stepper motors, with encoder-measured diameter and transducer-measured actuating force.
Blockwise's production-proven air-actuated balloon wrapping (aka folding) machine for pleating and compressing catheter balloons.
The world's most intuitive balloon wrapping machine pairs a high-performance microcontroller with a touchscreen HMI to provide complete and fully configurable balloon wrapping.
Recipe control ensures ease of use for the operator, while a secure calibration and manual mode ensures easy recipe setup and R&D use.
Our workhorse balloon wrapping machine with microcontroller and touchscreen HMI provides intuitive and flexible control of the balloon wrapping process.
A low-cost, fully-manual, air actuated balloon wrapping machine for pleating and compressing catheter balloons.
This fully manual balloon wrapping machine contains all the necessary settings for complete optimization of the balloon wrapping process, without electronic control or computerized timing.
Using a stopwatch to control the timing of pleating, compression, pressurization, and vacuum, the process engineer or the low-volume manufacturer can get the same results as on the recipe-driven VC machine.
A stent crimping machine compresses balloon-expandable stents, thereby attaching the stent to the balloon catheter.
Stent crimpers are generally comprised of two parts: the "compression station" - a mechanism that provides a variable-diameter, cylinder-shaped opening - and the "machine base" that controls the process.
These machines also serve as general-purpose radial compression machines for various other applications.
They can have a film sheathing option that protects fragile product surfaces during crimping.
