SILICA SOL INVESTMENT CASTING CAPABILITY

1、OUR CASTING CAPABILITY

(1)Depth of casting hole

Through Hole

2mm≤D<4mm H≤2D

4mm≤D<8mm H≤4D

D≥8mm H≤5D

Blind Hole

2mm≤D<4mm L≤D

4mm≤D<8mm L≤2D

D≥8mm L≤2.5D

Dmin﹦2mm


The scope can be enlarged by the use of pre-formed ceramic cores at additional cost,only economical for large quantities

(2)Minimum wall thickness:2mm(1mm for small area)

(3)Radius of Rounds and fillest

(4)Surface Roughness:Ra1.6-3.2

(5)Casting Weight:2g-50kg

(6)Annual output:600 tons

R0.3mm

R0.5mm


2、NOTES FOR CASTING-CONFIGURATION DESIGN

Equalize wall thickness

Avoid sharp change in thicknes

Avoid sharp angle

Avoid sharp angle

Avoid sharp angle

Avoid cross section

VALUE-ADDED SERVICES

If you are looking for a silica sol investment casting manufacturer to produce various construction and hardware-related accessories for you. Then we are your best choice.

To improve our services of investment castings and deliver finished products to our customers, apart from producing blank casting parts , we can also supply value-added services in below:

CNC Machining Service:

Machining is the process used to cut and manipulate raw material (blank investment casting parts) of a finished product to ensure precision for unique shapes. Cutting, drilling, forming, grinding, and more are used to create final machined investment castings.

Heat Treatment:

Heat Treatment is a method of controlled heating and cooling of metals to alter their mechanical and physical properties without changing the product shape.

Surface Treatment:

Products produced by silica sol investment casting technology have the advantages of complex shapes, high dimensional accuracy, surface finish and high dimensional accuracy. If products need extra surface Treatment,we can supply Polished galvanized, nickel-plated, electroplated, chrome-plated,Surface grinding, sandblasting, powder coating,Anodizing, acid treatment, polishing, DACROMET and so on .

Assembly Service:

Silica sol investment casting is the most common production method in modern industry. It can cast all kinds of complex and Precision casting. The common assembly services mainly for automobile parts, engineering components and other precision metal cast parts.

Testing Service
