Product Description
Custom Made Stainless Steel Casting Gear
Two types of investment cast processes: Silica Sol process and the water glass process.
The Silica Sol process is used to cast complex high quality parts with requirements of a very good surface finish and close dimensional tolerances.
This process can range from a weight of just a few ounces to approximately 80 pounds. If you are concerned with precision in very small parts, we are especially proficient at very fine detail work including teeth and serrations.
The water glass process is typical of the process in the early stages of investment castings. It generally is capable of much larger castings than the Silica Sol process, but does not have as good of surface finish or tolerances. The water glass process provides parts that have better surface finish and dimensional tolerances than sand castings.
This process may range in weight from several ounces to approximately 200 pounds.
First article layouts and spectrometer material certifications are provided with all first article samples.
Custom service: A variety of secondary operations can be performed on both types of investment castings. They include heat treatment, machining, plating, painting, polishing and buffing, assembly services and even custom packaging.

What are the limitations of using plastic gears in industrial settings?
Using plastic gears in industrial settings has certain limitations. Here’s a detailed explanation of these limitations:
- Lower Load Capacity: Plastic gears generally have lower load-bearing capacities compared to metal gears. They are more susceptible to deformation and wear under heavy loads or high torque conditions. This makes them less suitable for applications that require withstanding substantial forces or transmitting high power.
- Temperature Sensitivity: Plastic gears have temperature limitations, and their performance can be affected by temperature variations. Some plastic materials may experience dimensional changes, loss of strength, or reduced stiffness at elevated temperatures. Additionally, high temperatures can accelerate wear and reduce the lifespan of plastic gears. Therefore, plastic gears may not be suitable for applications that involve high-temperature environments or extreme temperature fluctuations.
- Environmental Sensitivity: Plastic gears can be sensitive to certain environmental conditions. Certain plastic materials may degrade or become brittle when exposed to specific chemicals, solvents, oils, or UV radiation. This restricts their use in applications where exposure to harsh chemicals, lubricants, or outdoor elements is common.
- Wear and Abrasion: While plastic gears can offer good wear resistance, they are generally more prone to wear and abrasion compared to metal gears. Under heavy-load or high-speed conditions, the surface of plastic gears can wear down, leading to a decrease in performance and potential failure over time. Additional measures, such as incorporating reinforcements or using lubrication, may be necessary to mitigate wear in certain applications.
- Dimensional Stability: Plastic materials can have lower dimensional stability compared to metals. They may experience creep, shrinkage, or expansion over time, which can affect the accuracy and reliability of gear operation, particularly in applications with tight tolerances or precise gear meshing requirements.
- Impact Resistance: Plastic gears may have limited impact resistance compared to metal gears. They can be more susceptible to damage or fracture when subjected to sudden impact or shock loads. This makes them less suitable for applications with high impact or heavy-duty requirements.
- Compatibility with Existing Systems: In some cases, replacing metal gears with plastic gears may require modifications to the existing system. Plastic gears may have different dimensions, mounting requirements, or gear ratios compared to metal gears, necessitating design changes or adaptations to accommodate the use of plastic gears.
Despite these limitations, plastic gears can still offer significant advantages in certain industrial settings, such as reduced weight, noise reduction, and cost-effectiveness. It’s crucial to carefully evaluate the specific application requirements and consider the trade-offs between the benefits and limitations of plastic gears when deciding whether they are suitable for a particular industrial setting.
Are there specific design considerations for using plastic gears?
Yes, there are specific design considerations that need to be taken into account when using plastic gears. Here’s a detailed explanation of these considerations:
1. Material Selection: Choosing the right plastic material for the gear application is crucial. Different plastic materials have varying mechanical properties, such as strength, stiffness, and wear resistance. Consider factors such as load-bearing requirements, operating temperatures, environmental conditions, and compatibility with lubricants. It’s important to select a plastic material that can withstand the specific demands of the application.
2. Gear Geometry: The design of plastic gears should consider factors such as tooth profile, module or pitch, pressure angle, and tooth thickness. The gear geometry should be optimized to ensure proper meshing, efficient power transmission, and minimal noise and vibration. The design should also take into account the limitations and capabilities of the plastic material, such as its ability to form precise tooth profiles and maintain dimensional stability.
3. Clearances and Tolerances: Plastic gears may require different clearances and tolerances compared to metal gears. The coefficient of thermal expansion, dimensional stability, and manufacturing processes of plastic materials can affect the gear clearances. It’s important to consider the thermal expansion characteristics of the specific plastic material and provide appropriate clearances to accommodate temperature variations. Tight tolerances may result in binding or increased friction, while excessive clearances can lead to backlash and reduced gear accuracy.
4. Load Distribution: Distributing the load evenly across the gear teeth is essential for preventing premature wear and failure. Consider gear design elements such as tooth profile, tooth width, and the number of teeth to optimize load distribution. Reinforcing the gear teeth with fillets or other strengthening features can help improve load-bearing capacity and reduce stress concentrations.
5. Stiffness and Deflection: Plastic gears generally have lower stiffness compared to metal gears. The design should consider the potential for deflection or deformation under load. It may be necessary to increase the gear size, modify the tooth geometry, or incorporate additional support structures to enhance stiffness and minimize deflection. Analytical tools and simulations can be employed to assess and optimize gear design for stiffness and deflection.
6. Lubrication and Wear: Proper lubrication is important for the performance and durability of plastic gears. Consider the lubrication requirements of the specific plastic material and design features that facilitate effective lubricant distribution. Pay attention to potential wear mechanisms, such as adhesive wear or abrasive wear, and incorporate measures to minimize wear, such as optimized tooth profiles, lubricant selection, and sealing mechanisms.
7. Environmental Factors: Plastic gears may be subjected to various environmental factors such as temperature extremes, humidity, chemicals, and UV exposure. Evaluate the potential impact of these factors on the gear material and design. Select plastic materials that offer resistance to environmental degradation and consider protective measures, such as coatings or encapsulation, to enhance the gear’s resistance to environmental conditions.
8. Manufacturability: Consider the manufacturability of plastic gears during the design phase. Different plastic materials may have specific requirements or limitations for manufacturing processes such as injection molding or machining. Design features that facilitate efficient and cost-effective production, such as draft angles, parting lines, and tooling considerations, should be taken into account.
By considering these specific design considerations, such as material selection, gear geometry, clearances, load distribution, stiffness, lubrication, environmental factors, and manufacturability, it’s possible to optimize the design and performance of plastic gears for various applications.
Can plastic gears replace metal gears in certain applications?
Yes, plastic gears can replace metal gears in certain applications. Here’s a detailed explanation:
Plastic gears offer a range of advantages that make them suitable alternatives to metal gears in specific scenarios. Some of the factors that determine whether plastic gears can replace metal gears include the application requirements, operating conditions, load capacity, and desired performance characteristics.
Advantages of Plastic Gears:
- Lightweight: Plastic gears are significantly lighter than metal gears, making them suitable for applications where weight reduction is important. This can lead to energy efficiency, reduced inertia, and lower wear on supporting components.
- Low Noise and Vibration: Plastic gears have inherent damping properties that help reduce noise and vibration levels during operation. This makes them suitable for applications where noise reduction is desired, such as in consumer electronics or office equipment.
- Corrosion Resistance: Certain plastic materials used in gear manufacturing exhibit excellent resistance to corrosion and chemicals. Plastic gears can be a suitable choice for applications in corrosive environments where metal gears may suffer from degradation.
- Self-Lubrication: Some plastic materials used for gear manufacturing have self-lubricating properties. This reduces friction and wear between gear teeth, eliminating the need for external lubrication and simplifying maintenance requirements.
- Cost-Effective: Plastic gears can be more cost-effective compared to metal gears, especially in large-scale production. Plastic materials are often less expensive than metals, and the manufacturing processes for plastic gears can be more efficient.
- Design Flexibility: Plastic gears offer greater design flexibility compared to metal gears. They can be molded into complex shapes, allowing for custom gear profiles and tooth geometries, resulting in optimized performance and efficiency for specific applications.
Limitations of Plastic Gears:
- High Torque and Load Capacity: Plastic gears may not have the same torque and load capacity as metal gears. In applications requiring high torque or heavy loads, metal gears may be more suitable due to their higher strength and durability.
- High Temperatures: Plastic gears have temperature limitations depending on the chosen material. In applications with high operating temperatures, metal gears that can withstand the heat may be necessary.
- Precision and Positioning: Plastic gears may not offer the same level of precision and positioning accuracy as metal gears. Applications that require tight tolerances and precise gear meshing may still require metal gears.
In summary, plastic gears can replace metal gears in certain applications where their advantages align with the specific requirements and operating conditions. It’s crucial to carefully evaluate the application needs, load capacity, temperature range, and other factors to determine if plastic gears are suitable replacements for metal gears.
