Raga Jet cooling core pin:

Raga have inhouse gun drilling machine 

Raga give 100 % inspection report of hole concentricity for Jet cooled core pin.

Hole Diameter : Ø2, Ø2.5, Ø3, Ø3.5, Ø4, Ø4.5, Ø5, Ø6 mm 

Hole Length: Max. 600mm. 

Hole Length/Diameter Ratio : 110 

Outer Diameter: Min Ø4 mm & Max Ø300 mm

Concentricity : 0.3 TIR

Why Core pin Polishing?:

  1. Rough surfaces have high surface temp compared to smooth or depressed surfaces. Core pins with rough surfaces have a high tendency of soldering.
  2. Rough surface of core pin catch casting during ejection.
  3. Grinding operation creates line marks that are perpendicular to ejection of casting. Which  opposed to ejection of casting 

Two Polishing option with Raga core pin

Draw Polish: Ra – 0.08 µm,This will help to eject casting smoothly 

Fine Polish: Ra -0.03 µm,  Help to minimize reduce soldering.

Core Pin Breakage Detection Device

Core pin breakage is a critical concern in die casting processes, as it can lead to major accidents. Detecting core pin breakage before the introduction of water in the High-Pressure Die Casting (HPDC) cycle is crucial to preventing such accidents.

The Raga Pin Breakage Detection Device (PBDD) plays a pivotal role in ensuring safety during casting operations. This innovative device utilizes an air cycle during casting injection to promptly identify any breakage in the core pin. By doing so, it provides an early warning system, enabling timely intervention to avert potential disasters.

One key advantage of Raga Pin Breakage Detection is its contribution to a safe environment for jet cooling. By swiftly detecting core pin breakage, the device facilitates a proactive approach to safety, allowing for effective management of the casting process.

Investing in the Raga Pin Breakage Detection Device not only enhances safety protocols but also safeguards against the consequences of core pin breakage, ultimately ensuring a secure and efficient die casting operation.

5 Horrible Mistakes You Are Making

  • Wrong surface treatment: 80 % lower life core pin due to wrong surface treatment selection.
  • Poor Design: up to 30% less jet cooling efficiency due to Poor design for cooling holes & jet cooler sizes.
  • Wrong supplier selection: 40% lower life of core pin due to inexperienced supplier selection for core pin.
  • Cheap Material use: 70 % lower core pin life due to the use of cheap material.
  • Poor water quality: Higher hardness of water results in scaling in jet cooled core pin.

It’s Time To Avoid These Mistakes With Raga

Success Stories

450 % Increase Life of core pin

One of the Die caster in India had a problem with core pin breakage after 2676 shots.

Raga studied and observed Core pin chamfer at starting of casting area -0.35 mm. The draft angle in core pin 0.75 °

Raga modify core pin design, Increases chamfer to 2 mm & draft angle 1.5°, and sends for approval.

The customer approved the design and gave the order. Raga supplied the core pin.

After the trial customer reported first core pin broke after 12476 shots.

Reduce Soldering without jet cooling

A Die caster in India had reported frequently soldering issues in 2 core pins of one mold.

Raga studied and observed after 673 shots core pin temp was rising up to 590°C. The core pin material was H13 and no surface coating.

Raga supplied core pins with high thermal conductivity hot die steel, Mirror Polishing and PVD coating.

Die caster run these core pins and reported no soldering issue upto 6572 shots.

0.5 % Rejection reduce due to shrinkage porosity

Smooth supply chain with Core pin coolers delivered within 4 to 6 weeks

One of the biggest die casting mold manufacturers in Taiwan had their mold deliveries delayed. This was due to 8 to 10 weeks delivery lead time from their existing Core pin supplier.

Raga had a detailed discussion with the customer understanding their material, surface treatment and monthly consumption. Raga’s dispatch period of 4 to 6 weeks helped them dispatch their molds in time.
