Castella — AI for real shopfloor casting Stop wasting shifts on guesswork. Castella helps foundry technicians and engineers create reliable production parameters for low-pressure die casting and other casting processes — fast, practical, and built for the shopfloor. Why Castella? No extra sensors or hardware required — works with the data you already have. No expensive, slow simulation software — get usable parameters in seconds. Designed by people who work on the floor: prioritizes simple, actionable settings (cooling start/sequence, phase pressures, phase times, total cycle time, region-based cooling, etc.). Reduce trial-and-error, scrap, and rework — increase first-run success. Core features Instant parameter proposals: enter your mold, material, and basic timing/geometry info and get a full parameter set (pressure phases, phase times, cooling schedule). Region-aware cooling: specify mold regions or feeder locations; cooling recommendations start from the farthest mold surface toward the feeder to optimize solidification. Safety & sanity checks: built-in validation warns about unrealistic inputs (e.g., implausible melt temperatures or impossible phase settings) so you don’t run a questionable recipe on the shopfloor. Expert feedback loop: accept, tweak, and save parameters — the system learns from your validated setups and improves over time. Collaborative contributions: share best practices within your team or company so knowledge stays on the floor, not just in one person’s head. Customizable templates: create and recall templates for common molds, alloys, and lines to speed setup. Clear, shopfloor-friendly UI: large touch targets, quick adjustments, and concise parameter summaries for operators. Who it’s for Foundry technicians and shop supervisors who need reliable parameters quickly. Production engineers who want to reduce setup time and variation. Small foundries that can’t afford high-cost simulation suites or extra instrumentation. How it helps you right now Replace “try and fail” cycles with data-backed suggestions. Cut the time between machine setup and a good casting. Reduce dependency on one “expert” by capturing team knowledge in the app. Save money by avoiding unnecessary sensors, third-party simulation licenses, and costly mistakes. Real shopfloor thinking Castella was built with shopfloor realities in mind: minimal inputs, immediate outputs, and clear warnings when a setting looks wrong. It emphasizes practical improvements you can implement today — not theoretical scenarios you’ll never test. Getting started Create a mold profile (or choose a template). Enter alloy, melt temp, and basic geometry/region info. Tap “Generate Parameters” and review the suggested cycle. Adjust, validate on one trial, then save the optimized recipe. Privacy & safety We respect your process data. You control whether recipes stay local to your device or are shared with team members. Castella includes safeguards to prevent obviously unsafe or implausible parameter sets. Join the new way to set up castings — faster setups, fewer rejects, and knowledge that stays on the floor. Download Castella and make your next cast the right one.

Verdict
The clearest difference is in-app purchases: Castella at none against Aphid's 4. Castella also leads on update cadence (every 5 days vs every 3 weeks). On price, ads, device support and iOS requirement there is nothing between them.
