SJ-MFG offers customized manufacturing services for various types of gears, including spur gears, rack gears, helical gears, bevel gears, worm gears, and more. Meet the various types of customized processing requirements for gears from customers.
Spur gear is a classic type of gear. The toothed part is parallel to the center axis, and the toothed recessed part is not upright. This design can reduce the speed and torque difference between gears when they mesh with each other, increasing the utilization of power
Helical gears are a type of component in the meshing method of spiral gears, featuring good meshing performance, smooth transmission, and low noise. Therefore, it is widely used in high-speed and heavy-load situations.
Bevel gears are used for transmission between intersecting shafts and can change the direction of transmission compared to cylindrical gears. Bevel gears are divided into straight-slot conical gears and helical conical gears, etc.
The worm gear mechanism is often used to transmit motion and power between two intersecting shafts. If a larger gear reduction ratio is desired, a worm should be used.
The gear-rack mechanism is used to transmit motion and power between any two shafts. It has a large transmission capacity, long service life, and high reliability; it can ensure a constant transmission ratio and can transmit motion between any two shafts at any angle.
The gear with teeth on the inner circle is an internal gear. Usually, in an internal meshing gear mechanism, the gear on the gear ring is an internal gear.
Low density, light weight, high strength, good electrical and thermal conductivity, excellent corrosion resistance, good appearance, and easy for CNC machining.
Easy to process and shape, good stability, resistant to chemical corrosion, excellent surface quality, good mechanical properties, resistant to impact and external forces
SJ-MFG offers a wide range of surface treatment options, which are applied to the surface treatment of 5 axis CNC parts. The main purpose is to meet specific functional requirements, enhance the appearance color, and improve the chemical and corrosion resistance of the part surface.
A protective oxide layer is formed on the surface of metal products, which is corrosion-resistant, wear-resistant, has a variety of colors and a beautiful appearance. It is most commonly used for aluminum alloy materials.
Using the impact effect of high-speed sand flow to clean and roughen the surface of the parts, a certain degree of cleanliness and different roughness can be achieved, and is applicable to both metal and plastic materials.
Heated in a high-concentration chemical solution, it forms a dense protective film, which is used to enhance the corrosion resistance, improve the appearance and minimize light reflection. It is commonly used for steel and stainless steel materials.
Enable the powder paint to adhere to the parts, forming a hard coating film on the surface. The coating thickness is uniform and it is wear-resistant. It is commonly used for metal parts.
Liquid paint is sprayed onto the surface of the parts by compressed air. It is widely used for surface coating of products such as automobiles and electronics, and is applicable to both metal and plastic materials.
Coating a layer of another metal on the surface of the metal part, such as nickel, chrome, gold, zinc plating etc, it is corrosion-resistant, wear-resistant and has a beautiful appearance. It is suitable for metal parts.
Based on the surface treatment with chemical plating solution, the parts are immersed in the plating solution to form a metal film, no need for electricity. Suitable for metals and a few plastic materials (ABS, PP, PC).
Using the charged particles in the solution to form a uniform coating on the surface of the parts. Suitable for metal parts.
Reduce the surface roughness of the parts and achieve a shiny, smooth and mirror-like surface effect. Applicable to metal parts and plastic parts.
By grinding the surface of the parts to create lines, a fine and lustrous effect is achieved. Applicable to metal parts.
Using high-energy-density lasers to irradiate specific areas of the parts, special marks are left. Applicable to metal and plastic parts
Press the screen-printed plates with graphics and text onto the surface of the parts, and offer a wide range of color options. Suitable for metal and plastic parts.
SJ-MFG adheres to a strict quality inspection process to ensure the precision and consistency of the manufactured parts.
Before the production begins, our engineering team will evaluate your part design. This includes aspects such as surface finish, structure, process, and other details of the drawings.
In precision processing, a on-site inspection system is maintained. The quality control team conducts size tolerance checks on all the parts being produced every hour.
For all completed orders, we can provide complete size inspection reports, material reports, hardness tests, RoHS certifications, etc. as per your requirements.
Ensuring that the parts we manufacture are of the highest quality is important. Four layers of protection: 1. wrapping paper 2. EPE 3. foam 4. paper/wooden box are applied during the packaging process, ensuring that we deliver the most high-quality and beautiful parts to you.
The factors influencing the cost of gears and components include the following:
The material, different metals and plastics have different prices.
The complexity and precision requirements of the gears.
Quantity, the unit price of samples is higher than that of mass production.
Heat treatment and surface treatment are required.
Tolerances and inspection standards.
