Introduction

PA46 is a heat-resistant grade of nylon PA. It is a high-melting-point and high-rigidity nylon with outstanding heat resistance and wear resistance. It is suitable for the periphery of engines and heat-resistant structural components.

The melting point of PA46 is approximately 295℃. It features a fast crystallization speed and high rigidity. Its long-term service temperature is higher than that of PA66, making it suitable for peripheral functional parts of engines.

Typical application fields

PA46 grade is often used in the following fields and scenarios. Our CNC machining services can provide customized parts for these industries.

Engine peripheral parts
Heat-resistant gear
Clutch device
Heat-resistant shell
Turbocharging component
Electronic heat-resistant parts

CNC Machining Guide

The following are the key process points for processing PA46 grade to ensure the quality of parts and processing efficiency.

1Tool selection

Select sharp single-edge or double-edge carbide tools with large relief angles, positive rake angles, and polished cutting edges. The fiberglass/carbon fiber-filled grades need to be equipped with wear-resistant coated blades.

2Cutting parameters

High-speed, medium-low feed, and small-depth layer-by-layer cutting are carried out. The cutting temperature must be strictly controlled below the material's softening point to prevent melting and tool sticking.

3Cooling and lubrication

Give priority to compressed air or cold air cooling; Most plastics are not suitable for coolant (as it can easily induce stress cracking), and only atomization lubrication should be used when necessary.

4Clamping scheme

Low clamping force in combination with soft claws or vacuum suction cups prevents deformation and indentation of thin-walled parts. Pay attention to the state adjustment of moisture-absorbing materials (such as nylon) before processing.

5Quality control

The coefficient of thermal expansion of plastics is large, and CMM needs to be measured in a constant temperature environment. Focus on internal stress, surface quality and dimensional stability.
