Bolang is a leading manufacturer and exporter of a wide range of gravity die casting products
- We offer our customers complete in-house machining (on CNC & Conventional
Machines), the convenience of testing facilities and vacuum impregnation
- specializing in manufacturing of INTAKE Manifolds for automobile engines. With a capacity range of 50 gms to 10 kgs
- We use both Manual (heated) and Automatic (cold) Core Box Process Machine to produce the cores.
- We have relevant expertise to make gravity die casting as per international standards adopted to produce
industrial die casting globally.
- Gravity Die Casting is the most viable route for the production of small to medium volume castings, which are uneconomical for
the high pressure process.
- Our system is capable of producing die castings in alloys of aluminium & zinc, which consistently turn out accurate, cleanly
defined metal parts in smooth or textured surfaces..
The component can be produced in either Aluminium or Zinc. Using a permanent mould called Gravity Die Tooling. Gravity Die Castings are produced by molten metal entering an aperture in the Gravity Die Tooling, this aperture allows metal to enter the cavity to form the cast shape of the Gravity Die Casting required by the customer.
Gravity Die Casting produced in all grades of Aluminium and Zinc. Higher volumes of precision castings are achievable using the Gravity - Die Casting, external or internal is either produced by means of a purpose made steel core or as previously mentioned an Airset sand core.
Gravity Die Castings produced are cost effective for quantities of a semi to high volumes. The finishing operations on a Gravity Die
Casting are minimal compared to a conventional sand casting, usually on a Gravity Die Casting the joint line is minimal and in some circumstances the need for an operation is not required.
Mechanical means are some times required for opening and closing of Die Tooling if the Gravity Die Casting to be produced is large and complex.
Gravity Die Castings if required by specification can be heat treated to adjust or improve its characteristics
Improvement to production rates of Gravity Die Casting can be improved by the use of multiple tooling.
A Gravity Die Tooling is able to produce Gravity Die Castings for several years without the need of refurbishment.
