Sweina - Bluetooth Industrial Metal Casting & Alloy Furnace Controller

Android companion app that connects over Bluetooth to a SWEINA industrial metal-casting / induction furnace controller, letting operators run and monitor melting processes in Auto, Manual, and Alloy-Making modes, set melting temperature and hold times, manage casting programs, and view run history.

01 Overview

Android companion app that connects over Bluetooth to a SWEINA industrial metal-casting / induction furnace controller, letting operators run and monitor melting processes in Auto, Manual, and Alloy-Making modes, set melting temperature and hold times, manage casting programs, and view run history.

Scope of delivery

Built the Sweina Android app in Kotlin that pairs with an industrial SWEINA furnace/bluetooth controller. Implemented Bluetooth device discovery and command-based control for heat, churn, vacuum, turbo, casting, gas and chamber operations, and built the Auto Mode, Manual Mode, Alloy Making, Mimic panel, checklist, calculator and history screens that operators use to manage the melting process.

02 Business Challenge

Delivering a production-grade industrial furnace control app required reliable Bluetooth control, precise melting-process management, and dependable release workflows.

03 Our Solution

Led and delivered Sweina, an Android (Kotlin) app that connects to a SWEINA industrial casting / induction furnace over Bluetooth, providing Auto, Manual, Alloy-Making, Mimic, checklist, calculator and history modules for managing the melting process.

Engineering approach

Engineered a Bluetooth command protocol (HEAT/CHURN/VACUUM/TURBO/CASTING/GAS/CHAMBER) with a class-based helper and a live status radar view. Persisted melting programs and auto-mode recipes with a Room database (Program/ProgramDao) providing offline access, and used Android Navigation + Data Binding for a clean multi-fragment industrial UI.
