Investment Casting Straight Miter Gears Spiral Bevel Tooth

Investment Casting for High – Quality Gears

Investment casting is the core process in manufacturing our outstanding Straight Miter Gears. This precision casting technique ensures that each gear is produced with the highest level of accuracy, meeting the stringent requirements of diverse applications.

Gear Profile and Design

Our Straight Miter Gears are characterized by a spiral bevel tooth profile. When combined with the helical gear design, it enables smooth and efficient power transmission. The spiral bevel tooth profile effectively reduces noise and vibration during operation, thus enhancing the overall performance of the gears.

Material Excellence

We utilize 20CrMnTi and its equivalent material grades for these gears. 20CrMnTi is well – known for its good hardenability, high strength, and excellent wear – resistance. This material endows the gears with the durability necessary to endure heavy – duty applications.

Surface Finish: Carburizing and Quenching

The surface finish of our gears is accomplished through carburizing and quenching. This process significantly increases the surface hardness of the gears while preserving their core toughness. The carburizing and quenching treatment enhances wear resistance, fatigue strength, and the overall service life of the Straight Miter Gears. Whether employed in automotive transmissions, industrial machinery, or other mechanical systems, our investment – cast Straight Miter Gears, with their spiral bevel tooth profile, made of 20CrMnTi and featuring carburizing and quenching surface finish, are engineered to offer reliable and long – lasting performance.

Here are some equivalent material grades of 20CrMnTi in different standards:

1. ISO (International Organization for Standardization)

20MnCr5 is quite similar. It has a comparable chemical composition and mechanical properties. The main alloying elements in both steels are manganese (Mn), chromium (Cr), and titanium (Ti), which contribute to hardenability, strength, and wear – resistance.

2. German Standard (DIN)

In the German DIN standard, 20MnCr5 is the equivalent grade. It is widely used in the automotive and machinery industries for components like gears and shafts, just like 20CrMnTi.

3. American Standard (AISI / SAE)

There isn’t a direct one – to – one equivalent, but steels like 5120H can be considered in the same general class. However, 5120H has a slightly different chemical composition, with less manganese compared to 20CrMnTi, and it may require some adjustment in heat treatment processes to achieve similar properties.

4. Japanese Standard (JIS)

SCM420H can be related. While not an exact match, it shares some similarities in terms of the alloying elements and can be used in similar applications after appropriate heat treatment to achieve comparable mechanical properties.

Investment casting, also known as lost wax casting, is a casting method in which a pattern is made of a melt-able material, then coated with several layers of refractory material to form a shell, and the pattern is melted away after high-temperature firing, and then the molten metal is poured into the shell.

Investment casting have high precision and high surface quality, with small machining allowances, which can achieve less or no machining requires. Investment casting can cast complex thin-walled parts with complex shapes (the minimum wall thickness can reach 0.25-0.4mm), and the smallest hole diameter can reach 2.5mm.

The process normal as below:

Drawing Review ->Tooling Designing ->Tooling Manufacturing ->Wax Pattern Making ->Pattern Tree Assembly ->Dipping and Coating ->De-waxing and Firing- Pouring-Knockout ->Grinding ->Heat Treatment -> Machining(if requires) ->Inspection->Delivery
