Auto parts are one of the main fields that our casting parts used. Most of the automotive parts are cast by high precision investment casting processing. In our foundry, we have silica sol lost wax casting processing, water glass lost wax casting processing and compound shell lost wax casting processing to meet the demand of auto parts.
The selection of water glass investment casting, silica sol investment casting and composite shell investment casting processes for automotive components primarily depends on precision requirements, surface quality, material, structural shape and cost budget. The water glass process is economical while with low precision, the silica sol process is high precision surface obtained. The composite shell process balances precision and the cost.

auto parts cast by silica sol process
The character of the auto parts produced with silica sol casting process has high-precision, high-surface-quality, core load-bearing, precision alloy castings for automobiles.
Then what kind of factor for us to consider whether the steel auto parts use silica sol casting process? Core fitting parts, precision thin-walled automobile parts, small precision parts, heat-resistant alloys, stainless steel precision parts and high end niche/custom parts.
Auto parts we cast by silica sol casting includes the engine system parts in Automotive: Turbocharger Housings (stainless steel/heat-resistant alloys), intake Manifold, Camshaft brackets, valve cover supports, oil pump bodies, fuel rail seats etc.
Braking system in Automotive are made by silica sol investment casting process includes: passenger car hydraulic brake calipers, caliper pistons, master cylinder, electronic parking brake brackets.
In this system, the auto parts cast by silica sol lost wax cast includes: high-end passenger car steering knuckles, suspension ball joint seats, small precision differential housings, universal joint yokes, half-shaft flanges.
The high end exhaust system of the car are cast by silica sol casting process, includes the auto parts: integrally cast stainless steel exhaust manifolds for passenger cars, three-way catalytic converter housings, precision-fitting exhaust joints.
Some of the auto parts used in new energy vehicles specifically, like the automotive parts precision motor end covers, electronic control housing connectors, high-precision aluminum alloy battery pack brackets.
auto parts cast by Sodium Silicate (Water Glass) Process
The character of the auto spare parts produced with water glass shell casting process has low precision, large-size, non-core load-bearing steel castings for automotive vehicles.
Then what kind of factor for us to consider whether the steel auto parts use sodium silicate(water glass) casting process? Low precision structural parts, large rough parts(>800mm), ordinary carbon steel cast, mass-produced economy auto parts.
The automotive parts cast by silica sol investment casting process includes: leaf spring shackles, brackets, rear axle housing connectors, suspension supports, balance shaft brackets
Some of the braking parts in car and motor industry are cast by water glass casting: economy commercial vehicle brake calipers, brake backing plates, brake cylinder brackets.
The auto parts include exhaust manifold blanks(requiring subsequent machining), muffler brackets, engine mount brackets are produced by water glass casting(sodium silicate casting) in Dalian lantian foundry.
The auto parts are produced in Lantian precision machinery foundry includes door hinge bases, frame connection brackets, spare tire carriers, trailer hitch bases.
In Commercial motor cars, some steel parts are cast with water glass shell casting: drive shaft brackets, leaf spring seats, economy wheel hub bearing seats.
auto parts cast by Composite Shell Process
The character of the auto spare parts produced with composite shell casting process has medium high precision, complex structure, cost-quality balanced core castings for automobiles.
Then what kind of factor for us to consider whether the steel auto parts use composite shell lost wax casting process? The answer is medium-precision complex parts, medium-to-large parts(300mm~800mm), mid-to-high end mass produced core auto parts.
In auto motor industry, the parts cast considered with composite shell investment casting process mainly include cylinder head covers, rocker arm supports, injector seats, water pump bodies, thermostat housings, turbocharger intermediates.
The steel braking parts cast by composite shell process include mainstream passenger car brake calipers, brake caliper brackets, brake disc flanges, ABS sensor seats.
Control arms(wishbones), tie rod ball joint seats, suspension bushing seats, shock absorber lower supports, stabilizer bar brackets etc steel components in automotive motors are produced by composite shell casting process.
The auto spare parts are fabricated in the precision casting foundry include: clutch housings, transmission shift forks, drive shaft flanges, differential supports.
The stainless steel exhaust manifolds for commercial vehicles, passenger car exhaust transition pipes, precision muffler joints in the automobile can be cast by composite shell investment casting process.
