We are offering investment casting components in ferrous/non ferrous metals & alloys made through lost wax process. We are capable enough to produce casting components with weight range from 10 gms. to 25 kgs. Our product range includes:

• Air Compressor Components
• Textile Machinery Parts
• Marins Machine Parts
• Pump Parts
• Turbine Engine Components
• Valves
• Pneumatic Tools
• Spare Engine Parts

Our manufacturing, production processes and quality control tests are backed by a team of highly qualified and experienced technocrats and professionals. Our workforce understand the different requirements of investment casting and its different stages. Utilizing the knowledge and experienced background, our team is capable to produce customized products to fulfill varied customer needs and has the necessary infrastructure to market its products throughout the world.

At Fine Diewax, strict quality control checks are carried out at different stages of production to see that all the process parameters are maintained. We also prepare & generate reports for different quality checks conducted by us. Some of the QC reports documented by us are:

• Die Inspection Report: Quality checking report of die inspection test. This report is not given to customer, however on request we can provide it to customer.



• Wax Pattern Inspection Report: This is documented batch wise & is used for our process controls only.



• Methoding System: In methoding system, the assembly details, coating, cycle, melting parameters are documented in forms of drawing. According to our policy of management, the report is not issued to the clients in any condition. In shelling schedule, number of coats, drying hours, viscosity of slurry, humidity & other things are recorded to check the different process parameters.

Investment casting process use lost wax process, it is a sophisticated technology where intricate and complicated components can be produced in excellent shapes and finishes. Investment casting leads to closer dimensional tolerance, reduced machining allowance and helps in achieving increased productivity and better cost-realization.

The technique has got utilities in various industries and has got following salient features:

• Freedom in design alloy selection.
• Smooth surface finish and close dimensional tolerances.
• Letterings and numbering on castings is possible.
• Zero leakage in all castings.
• Eliminate/reduce machining operation.
• Suitable for batch as well as mass production.
• Casting weight from 5.0 gms to 32 kgs
• Minimum wall thickness 2.5 mm possible.

Fine Diewax Casting Limited is an investment castings manufacturer, hence it is essential to cater the castings of intricate shapes with precise tolerances as per IS:11199:1984. To achieve this objective, it is unavoidably important to maintain strict quality control procedures throughout the manufacturing process.



We have variety of testing equipment to ensure production & supply of zero-defect products, like:

• Meters for Metal Temperature
• Hardness Tester
• Viscosity Cup
• Multi Meter
• Vernier Calipher
• Micro Meter
• Surface Plate
• Micro Weighing Machine
• Carbon Sulpher Aparters
• Muffle Furnace
• Mini Oven
• Hot Plates
• Glass Wares & beakers

The company has separate departments for die development, shelling, pattern moulding department, felting department, melting department, die waxing department.

Proper checking is done at the time of assembling the pattern. Depending on the type of components slurry coatings are done to prepare the shells. On every occasion of coating, proper checking is carried out & each shell is checked & sand, dust & other particles are removed.



We spend a big share of our revenues on continuous R & D to keep pace with changing environment and technology and ever increasing competition. The research team is constantly involved in developing new methods for improving each process of investment casting. The team also helps us to reduce rejection level, which always remains on higher side in investment casting process.

Various quality control checks are minutely carried out at different stages of production to ensure defect free products.

• Die designs are carried out after proper analysis of product drawing or sample. To obtain the dimensions & features of a product at the end of process, it is essential to add proper shrinkage allowance to every dimension. After inspection, if the die is find good by quality checking department, it is sent to the pattern moulding department for sampling process.
• Wax preparation is done with suitable mixing to get hardness & to make sure that the same is melted at certain temperature.
• For slurry preparation: viscosity checking & proper mixing of zercon flour & silica solution is done to ensure stirring for the stipulated level of duration.
• Each wax pattern is inspected for accurate formation & breakages. Different patterns are individually checked & unwanted portions are replaced.
