Die-Casting Technologies & Consumables
RAGA supplies jet cooling, vacuum and mold-cooling monitoring systems, alongside high-life mold consumables for solving your toughest die-casting challenges.
Still losing your money and peace to porosity?
A porous casting fails late, after the metal, the machine time and the machining have already been paid for. Scrap that piles up at the leak tester. Cores pulled and molds opened for unplanned rework. Trays quarantined by your customer while your line waits for the verdict.
Each shot that should have been a part is instead a cost, and every rejection chips away at the confidence that won you the contract.
Shrinkage porosity
As metal solidifies, it contracts. When enough liquid metal cannot feed the last-solidifying regions, internal shrinkage voids can form.
Gas porosity
Air in the shot sleeve and cavity can become trapped during filling, forming pores that may cause leaks or blisters after machining or heat treatment.
Two product families for the die-casting process
Technologies that control cooling, vacuum and process quality at the mold, and consumables fitted inside the tooling. Designed to work together.
Machines and systems working with your DCM and tool
Jet cooling unit
High-pressure water and air purge to jet-cooled core pins, minimizing shrinkage porosity in your critical areas.
- RAGA PRO
- Entry-level machine; 20 pins, 2 systems
- RAGA NEX
- Plug-and-play; international standards and spares
- RAGA NEXplus
- Process-controlled closed loop with temperature control and scale-free system
Vacuum unit
Evacuates air from the shot sleeve and mold to reduce gas porosity; machines from 600 t to 3,200 t.
- RAGA UNO
- Plug-and-play entry to vacuum die casting; up to 800 t
- RAGA VACMAX
- Two-stage evacuation from shot sleeve and mold
- RAGA VACEXT
- Extension unit near the mold for high tonnage; up to 4 per unit
Monitoring system
Per-line flow and temperature every shot: detects real-time blockage, breakage and leakage in jet, spot and line cooling.
- Channels
- 4, 8 or 16
- Compatibility
- Works with any jet cooling machine
- Line devices
- Pin Breakage Detection, Visual Flow Manifold, Block Type Manifold
AquaControl and Cool Leak Test
Water conditioning and offline testing that keep cooling lines scale-free and leak-free.
- AquaControl
- Water temperature and conductivity control; closes the loop on new or existing jet cooling machines
- Cool Leak Test
- Offline PLC-based test of jet cooling lines at 18 bar with air pressure-drop leak test
High-life components inside the tooling
Core pins
Long-life and jet-cooled core pins with deep-hole concentricity.
- Material
- AISI H-13 / DIN 1.2344
- Finish
- Precisely machined and ground; vacuum heat treatment, nitriding and coating options
Jet coolers and spot coolers
Cooling inserts fitted inside the tooling to direct water where shrinkage porosity forms.
- Jet coolers
- Six variants: thread, O-ring, compact thread, compact O-ring, rotating and isolated types
- Spot coolers
- For larger cooling channels; stainless-steel heads for longer life and less clogging
Injection parts
High-life components for the shot end of the machine.
- Shot sleeves
- Standard and vacuum shot sleeves
- Plunger tips
- Custom-made to machine and alloy
- Gating parts
- Sprue bushes and diffusers
Products developed from close analysis of the die-casting process
For over thirty years, RAGA has served OEMs and Tier-I die-casting companies around the world. Every product in our range is developed from close analysis of the die-casting process and the environment it runs in.
Our customers cast engine blocks, crankcases, transmission housings, battery and motor housings, pump and valve parts, structural parts, among many other components.
Application-focused, not just equipment supply
- A connected range: cooling and vacuum machines alongside the core pins, jet coolers, manifolds and injection parts used with them.
- Process control built in: closed-loop temperature control, water-conductivity control, per-line flow monitoring and leak testing.
- Devices that work with existing equipment: monitoring systems, AquaControl and pin-breakage detection integrate with non-RAGA jet cooling machines.
- Technical support for application selection, mold adaptation, installation and spares.
