6 Qualification Steps

3 Process Types

DOE Statistical Design

MIT Open Source

Core Capabilities

Everything you need for
systematic polymer research

Built for process-specific qualification and DOE workflows — from initial rheology checks to optimized process windows.

Scientific Molding Qualification

Injection uses the structured 6-step Scientific Molding protocol. Compounding and coating use independent process-specific qualification packs.

Injection-first · Process-specific packs

Design of Experiments (DOE)

Configure factors and levels, auto-generate run lists, enter results, and get instant statistical analysis with heatmaps and 3D response surfaces.

Full Factorial · Screening

Report Generator

Create editable, structured reports per experiment with embedded charts. Multiple reports per experiment, with digital signature workflow.

Tiptap Editor · Charts

Kanban Task Manager

Track experiment tasks across Init / In Progress / Done / Failed columns. Link tasks to qualification steps, DOEs, and reports with due dates.

iCal · Google Calendar

Role-Based Access Control

Five roles — admin, manager, engineer, operator, viewer — with granular access to processes, experiments, and entity assignment.

Passport.js · bcryptjs

Lab Journal & Notes

Rich note-taking with entity linking — attached to experiments, qualification steps, DOE studies, runs, or reports. Full journal feed with search and filtering.

Daily Mode · Soft Delete

Core Workflow

From process setup
to optimized parameters

A clear, linear path through process qualification and DOE — every step documented and traceable.

Create a Process & Experiment

Set up your polymer process (injection, compounding, coating) and create an experiment with machine assignment and recipes.

Run 6-Step Qualification

Execute the process qualification pack — each step has its own setup, run list, and data entry screen.

Design & Run DOE Studies

Configure factors and responses, generate run lists automatically, enter data from the machine, and analyze statistically.

Review Analysis & Charts

Explore interactive ECharts — main effects, interaction plots, heatmaps, and 3D response surfaces where applicable.

Generate & Sign Reports

Build structured reports with embedded charts, edit them with a rich text editor, and collect digital signatures from the team.

Process Library

Three polymer processes now,
one unified platform for many more

Each process type has its own tailored qualification pack and DOE defaults. New process templates can be added as the library grows.

PROCESS TYPE 01

Injection Molding

Scientific Molding methodology. The full 6-step protocol developed by Suhas Kulkarni for robust, repeatable injection molding processes.

Rheology / Viscosity Curve
Cavity Balance
Pressure Drop Study
Cosmetic Process Window
Gate Seal Study
Cooling Time Optimization

PROCESS TYPE 02

Twin-Screw Extrusion

Compounding qualification adapted for twin-screw extruders. Maps the energy window, thermal history, and mixing quality.

RTD / Residence Time Stability
SME Map / Energy Window
Melt Temperature / Thermal History
Feeding / Side-Feeder Qualification
Degassing / Moisture Control
Dispersion / Mixing Quality Check

PROCESS TYPE 03

Coating Processes

For water, solvent, and extrusion coatings. Qualifies the rheology window through to barrier and functional performance checks.

Rheology Window
Wetting / Surface Energy Check
Coat Weight Calibration
Drying / Curing Window
Adhesion Qualification
Barrier / Functional Check

Methodology Reference

Scientific Molding for
injection processes

Injection qualification in the platform follows the Scientific Molding approach. It is implemented as a dedicated 6-step workflow with process-specific screens and run tracking.
