Quality & Safety


Quality control in die-casting is an extensive process. Due to the various issues that the die casting process is prone to, quality control efforts must be tailored to the needs of individual products.

The die casting process has many failure modes which must be monitored and prevented.  Typical problems for die casting products include, but are not limited to:

Porosity opened up after machining creating leak paths.
Dimensional problems in the casting due to shifts, wear or moves in moving components in the die.
Appearance issues due to fill problems or die condition.
Trimming problems leaving excess material on the casting.
Leaking castings due to some combination of other issues.
Missed or improper secondary operations, such as painting or assembly.

Many different techniques exist to detect and prevent each of these failure modes.
Rheotech uses advance quality control measures to ensures the quality and safety of each component delivered to the clients.

Common Melting furnace

* Maintain 70:30 ratio
* Maintain metal temp within specs.
* Excellent control on melting process.

Nitrogen Degassing machine

* Degassing more effective.

Density Index Finder

* Validation of Degassing. Good melting practice.

Inhouse Spectro machine

* Excellent control on chemical composition of raw material.

Auto laddle

* Machine Automation for equal qty of metal pouring system in place. (POKE YOKE)

Auto spray

* Machine Automation for consistent spray. (POKE YOKE)

Interlocking of PDC machine w.rt. metal temp. At Holding Furnace

* PDC machine will not work when the metal temp below 640 deg C & above 680 deg C (POKE YOKE)

Die temp monitoring using Infrared thermometer

* Control of die temp at critical zones.

X-ray Inspection at Third party Lab

* Every new tools castings checked X-ray at critical zones to validate the die design.

Visual Insp. with 4X lens

* 100% Inspection for defects at critical zones.

Calorimeter to ensure the die coat concentration

* Control on diecoat concentration.

Trimming operation

* Automation at deburring process. (Poke Yoke)

Mould flow simulation study

* Control on diecoat concentration.


Industrial safety  refers to the management of all operations and events within an industry in order to protect its employees and assets by minimizing hazards, risks, accidents, and near misses. Industrial safety covers a number of issues and topics affecting safety of personnel and the integrity of equipment in a particular industry. The following functions are generally carried out at our factory.

General Safety – General aspects of safety which are common to all industries.
Occupational Safety and Health – Particularly associated with the occupation.
Process and Production Safety – To minimize accidents at workplace.
Material Safety – To minimize wastage of raw material and damage to finished goods.
Workplace Safety – Safety issues directly related to the workplace setting.
Fire Safety – To prevent loss of lives and property.
Electrical Safety – Arising from the equipment used.
Building and Structural Safety – Including installations as per existing building code.
Environmental Safety – Concerns the direct and indirect environmental impact of the industry.
