Specialized in spare parts of a feed screw extruder and expander.
Business Overview _ Process of screw parts
Process of feed screw extruder & expander's spare parts
Process of screw parts for feed machines
In order to make spare parts of the feed screw machine, it is made into a cast and processed or extruded raw materials and processed.
The following is the process of making parts of the feed extruder or expander using castings and extrusion materials.
Production Process(Casting Production)
Order receiving from customers
Upon receiving an order from a customer, the production department checks the specification
of the ordered product as well as production schedule.
Order confirmation and
start of casting work
Casting work begins after selecting an optimal casting material according to the item to produce and its usage.
Quality check of the casting product and conduct of primary processing
After checking the material property and quality of the casting product, rough machining is conducted to the inner and outer surfaces.
Checking of product dimension and conduct of secondary processing
The dimension of the product is precisely coordinated by conducting finish processing to the inner and outer surfaces.
Heat treatment of the product
Quenching and tempering processes to give hardness to steel and soften the structure of the steel
The product quality is enhanced by applying a heat treatment method suitable for the product.
Checking of product deformation after the heat treatment and
conducting of the 2nd finish processing (Grinding)
After checking of possible minute changes of the product size made by the heat treatment, the product dimension is coordinated again by conducting the grinding work on the inner and outer diameters so that the errors of the dimension fall within the allowed error limits.
Final product inspection (Product exterior and size)
After checking of possible minute changes of the product size made by the heat treatment, the product dimension is coordinated again by conducting the grinding work on the inner and outer diameters so that the errors of the dimension fall within the allowed error limits.
Inspection Report
Product shipping and vacuum packing
To prevent a damage or failure of the product that may occur during overseas transportation, products are shipped in a vacuum package and a wooden box.
Delivery (by sea or by air)
Products are shipped by sea or by air depending on the emergency. It takes about thirty to forty five days from the order receipt to the product delivery. (This lead time can be changed according to the ordering quantity and production schedule.)
Processing of Purchased Material (Processing of Round Bars)
Upon receiving an order from a customer, the production
department checks
The specification of the ordered product as well as production schedule.
Purchase of round bars
An optimal material is selected according to the item to produce
and its usage.
Round bar processing (Primary)
After checking the material property and quality of the bar, rough machining is conducted to the inner and outer surfaces.
Round bar processing (Finish)
The dimension of the product is precisely coordinated by conducting finish processing to the inner and outer surfaces.
Spline key processing
Special areas like spline key, etc.
are processed..
Heat treatment of the product
The product quality is enhanced by applying a heat treatment method suitable for the product.
Checking of product deformation after the heat treatment and
conducting of the 2nd finish processing (Grinding)
After checking of possible minute changes of the product size made by the heat treatment, the product dimension is coordinated again by conducting the grinding work on the inner and outer diameters so that the errors of the dimension fall within the allowed error limits.
Final product inspection (Product exterior and size)
Final product inspection is conducted to check if the product
has errors that fall within the structural error range.
