## What is PolyTakt?

PolyTakt is the shop-floor companion for injection molders, setting technicians, and process engineers. It is built for injection molding: scientific molding studies, process calculators, and references you can use at the press.

Core calculators, converters, and lookups run offline. No account is required for the toolbox. Metric and imperial units are both supported.

FREE TOOLS
• Shot size — volume and weight from melt density
• Clamp force — tonnage from projected area and material
• Cooling time — from part thickness
• Drying — dryer load and residence time
• Gate shear — gate size and fill time against shear limits
• Water flow — turbulent cooling in mold circuits
• Residence time and barrel utilization
• Melt density, shrinkage, pressure ratio, and production rate
• Process transfer — move a setup from one machine to another
• Material lookup — melt temperature, mold temperature, and drying data
• Troubleshooting — common visual defects and what to check next
• Purge and changeovers
• Vent assessment, platen clamp reference, and screw and barrel wear
• Converters — pressure, temperature, length, weight, screw speed, flow, torque, and density

SCIENTIFIC MOLDING
A structured workflow for a process you can repeat, not a setpoint that only looked acceptable on one shift. Free users can view the workflow in demo mode. PolyTakt Pro is where you run and save your own studies:

• Process setup
• Back pressure, screw speed, decompression, and feed throat
• Viscosity curve (in-mold rheology)
• Cavity balance
• Pressure drop
• Hold pressure
• Gate seal (gate freeze)
• Clamp force and cooling time
• Operating window (design of experiments)
• Process stability verification

POLYTAKT PRO
Individual Pro adds cloud sync, custom materials, process condition sheets, and the scientific study suite on your phone. Subscriptions are billed by the App Store.

Machines, molds, and saved setup data stay with your account, so the next shift is not starting from memory.

Understand the process, then make it hold. Download PolyTakt.
