The Advantage of Powder Metallurgy Process
1. Cost effective
The final products can be compacted with powder metallurgy method ,and no need or can shorten the processing of machine .It can save material greatly and reduce the production cost .
2. Complex shapes
Powder metallurgy allows to obtain complex shapes directly from the compacting tooling ,without any machining operation ,like teeth ,splines ,profiles ,frontal geometries etc.
3. High precision
Achievable tolerances in the perpendicular direction of compacting are typically IT 8-9 as sintered,improvable up to IT 5-7 after sizing .Additional machining operations can improve the precision .
4. Self-lubrication
The interconnected porosity of the material can be filled with oils ,obtaining then a self-lubricating bearing :the oil provides constant lubrication between bearing and shaft ,and the system does not need any additional external lubricant .
5. Green technology
The manufacturing process of sintered components is certified as ecological ,because the material waste is very low ,the product is recyclable ,and the energy efficiency is good because the material is not molten.
FAQ
Q1: What is the type of payment?
A: Usually you should prepay 50% of the total amount. The balance should be pay off before shipment.
Q2: How to guarantee the high quality?
A: 100% inspection. We have Carl Zeiss high-precision testing equipment and testing department to make sure every product of size,appearance and pressure test are good.
Q3: How long will you give me the reply?
A: we will contact you in 12 hours as soon as we can.
Q4. How about your delivery time?
A: Generally, it will take 25 to 35 days after receiving your advance payment. The specific delivery time depends on the items and the quantity of your order. and if the item was non standard, we have to consider extra 10-15days for tooling/mould made.
Q5. Can you produce according to the samples or drawings?
A: Yes, we can produce by your samples or technical drawings. We can build the molds and fixtures.
Q6: How about tooling Charge?
A: Tooling charge only charge once when first order, all future orders would not charge again even tooling repair or under maintance.
Q7: What is your sample policy?
A: We can supply the sample if we have ready parts in stock, but the customers have to pay the sample cost and the courier cost.

To be negotiated![]() What are the advantages and disadvantages of using screw gears?Using screw gears, also known as worm gears, offers several advantages and disadvantages. These gears have unique characteristics that make them suitable for specific applications but may also present limitations in certain scenarios. Here’s a detailed explanation of the advantages and disadvantages of using screw gears: Advantages:
Disadvantages:
When considering the use of screw gears, it is important to evaluate the specific requirements of the application, such as the need for high gear ratios, load capacity, positional accuracy, and noise levels. By carefully assessing the advantages and disadvantages, engineers can determine whether screw gears are the most suitable choice for their particular application. |

What is a screw gear and how does it work?
A screw gear, also known as a worm gear, is a type of gear mechanism that consists of a screw-like gear (called the worm) and a toothed wheel (called the worm wheel or worm gear). The screw gear operates on the principle of a helical screw driving a toothed wheel to transmit rotational motion and power. Here is a detailed explanation of how a screw gear works:
- Configuration: The screw gear consists of two main components: the worm and the worm wheel. The worm is a cylindrical gear with a helical thread wrapped around it, resembling a screw. The worm wheel is a toothed wheel that meshes with the worm. The orientation of the helical thread on the worm and the teeth on the worm wheel is typically perpendicular to each other.
- Meshing: The worm and the worm wheel mesh together by engaging the helical thread of the worm with the teeth of the worm wheel. The helical thread on the worm acts as a screw, and as the worm rotates, it drives the rotation of the worm wheel. The teeth on the worm wheel provide the necessary contact points for the meshing action.
- Transmitting Motion: When the worm rotates, the helical thread transfers rotational motion to the worm wheel. The helical thread of the worm pushes against the teeth of the worm wheel, causing the worm wheel to rotate. The direction of rotation of the worm wheel depends on the helix angle and the direction of rotation of the worm. The gear ratio between the worm and the worm wheel is determined by the number of teeth on the worm wheel and the pitch of the helical thread on the worm.
- Mechanical Advantage: One of the key characteristics of a screw gear is its ability to provide a high mechanical advantage or gear ratio. The helical design of the worm and the worm wheel allows for a large number of teeth to be engaged at any given time, resulting in a high gear ratio. This makes screw gears suitable for applications that require a significant reduction in rotational speed or an increase in torque.
- Self-Locking: A unique property of screw gears is their self-locking capability. Due to the helical thread design, the friction between the worm and the worm wheel tends to hold the gear system in place when the worm is not rotating. This self-locking characteristic prevents the worm wheel from backdriving the worm. It provides inherent braking or locking action, making screw gears suitable for applications where holding position or preventing reverse rotation is necessary.
- Efficiency and Lubrication: Screw gears generally have lower efficiency compared to other types of gears due to the sliding action between the helical thread and the teeth of the worm wheel. The sliding motion results in higher friction and heat generation. Proper lubrication is essential to minimize wear and improve efficiency. Lubricants with good adhesion and boundary lubrication properties are commonly used for screw gears.
Screw gears are widely used in various applications, including machinery, automotive systems, conveyor systems, lifting equipment, and many others. Their unique characteristics of high gear ratio, self-locking capability, and compact design make them suitable for specific applications where precise motion control, torque multiplication, or holding position is required.
