Peek material supplier11/24/2023 ![]() ![]() It is an important parameter and should be monitored continuously.Ģ. Injection time: This refers to the time required for the screw to move forward from the full injection position to the conversion position. The following three parameters can be monitored to ensure that the process is in control when injection molding acceptable parts:ġ. This ensures that both injection rate and fill time are controlled. Process control and monitoring: The molding process should be controlled by screw speed and position, not by pressure and time. The drying system should be able to maintain the recommended drying time in continuous operation, usually 6 hours under the above conditions.Ĥ. Material drying: The drying equipment must be able to reach a temperature of at least 120☌. If you need help with specific screw design and identifying a suitable screw manufacturer, you can contact Tianxie Industrial Co., Ltd. The recommended compression ratio is between 1:1 and 1.3:1. It is necessary to use a low compression ratio screw without a backflow device. ![]() Screw: The screw material has a temperature resistance of 400 degrees Celsius. Injection molding machine: It is recommended to use a modern reciprocating screw injection molding machine with closed-loop control capability and microprocessor control for injection molding of PEEK Tepla® T7200 engineering plastics.Ģ. There are high requirements for equipment, process control and operators.ġ. The injection molding characteristics of PEEK materials: high injection temperature, complex injection process, unstable product performance and other difficulties. High Temperature Resistance: When the process temperatures go beyond the limit of what conventional plastic materials can withstand, it is advisable to go for PEEK.Deep Mould can provide different shape of PEEK material part injection and mold toolings.īelow are some key points when you are ready for making the PEEK mold and PEEK part injection.Hydrolysis Resistance: PEEK material can be exposed for a long period of time tohigh pressure water and steam without exhibiting any serious degradation.It displays good friction as well as wear properties. Long Life: It is a hard, stiff and strong polymer.It can only be dissolved in concentrated nitric acid or sulphuric acid. Chemical Resistance: PEEK displays high resistance amidst a wide range of chemical environments, including high temperatures.Maximum continuous service temperature in air (☏)Ĭoefficient of linear thermal expansion (x 10-5 in./in./☏) Izod impact, notched (ft-lbs/in of notch) Bushings, bearings, seals, and back-up rings.This engineering plastic has a proven track record in challenging environments such as aerospace, oil and gas, and semiconductor. PEEK has the ability to maintain stiffness at high temperatures and is suitable for continuous use at temperatures up to 338☏ (170☌). It offers hydrolysis resistance to steam, water, and sea water. PEEK (polyetheretherketone) is a high-performance engineering plastic with outstanding resistance to harsh chemicals, and excellent mechanical strength and dimensional stability. PEEK can easily be fabricated to any close tolerance. It is a colourless organic polymer thermoplastic used in engineering applications. PEEK has outstanding chemical resistance as well as resistance to steam and hot water. PEEK (polyether ether ketone) is a strong, stiff plastic material that is often used in applications where performance at elevated temperatures is required. ![]()
