PEEK 150G (Glass-Filled) Polymer: Properties, Applications, and CNC Machining Guide

يُعد اختيار المادة الهندسية المناسبة أساسًا لأي مشروع ناجح في التشغيل بالماكينات ذات التحكم الرقمي. PEEK 150G is Glass-fiber-reinforced polyether ether ketone (PEEK), and it is specified across demanding industries because its property profile matches real service loads. In this guide we examine its chemical composition, mechanical and physical properties, where it is used in production, and the practical parameters our machinists apply when cutting, drilling and finishing it on modern CNC equipment. Whether you are specifying raw stock or validating a design, the data below will help you make a confident, cost-effective decision.

Understanding PEEK 150G also means understanding how it behaves once it leaves the saw and enters the spindle. The sections that follow move from metallurgy and chemistry to real machining advice, so you can plan tolerances, tooling and finishing in a single pass rather than discovering problems on the shop floor. For related processing topics, see our resources on تشغيل آلات دقيقة باستخدام الحاسوب (CNC) و اختيار المواد للأجزاء المخروشة.

We have machined PEEK 150G in quantities ranging from single prototypes to full production runs, and the guidance here reflects that hands-on experience. Numbers are representative of the common supplied temper; always confirm critical values against a mill certificate for the exact heat you receive.

التركيب الكيميائي وكيمياء السبائك

PEEK 150G is Glass-fiber-reinforced polyether ether ketone (PEEK). Its performance comes from a carefully balanced chemistry in which each element plays a specific role: major alloying elements build strength and hardenability, while minor additions refine the grain, improve machinability or stabilize the microstructure during heat treatment. The typical composition is shown in the table below, and we then explain what the most important elements do.

In PEEK 150G, base (typically PEEK matrix): the base polymer delivers the high-temperature and chemical resistance this family is known for. Controlling this element within tight limits is what lets mills deliver repeatable, specification-grade stock.

In PEEK 150G, filler (typically Glass fiber (typically ~10-15%)): the filler raises stiffness, wear resistance or electrostatic performance as required. Controlling this element within tight limits is what lets mills deliver repeatable, specification-grade stock.

In PEEK 150G, grade (typically Semi-crystalline reinforced): the grade is tuned for the intended balance of stiffness, toughness and cost. Controlling this element within tight limits is what lets mills deliver repeatable, specification-grade stock.

في عملية الإنتاج، يتم التحقق من التركيب الكيميائي باستخدام التحليل الطيفي وتوثيقه في شهادة المواد. وبما أن التغيرات الطفيفة تؤثر على قابلية التقسية، وسلوك التآكل، وكذلك استجابة المادة لأدوات القطع، فإننا نقوم دائمًا بمطابقة شهادة الحرارة مع خطة العملية قبل تحميل أول قضيب.

الخصائص الميكانيكية

Mechanical properties define how PEEK 150G carries load, resists deformation and survives fatigue in service. The values quoted here are representative of the common supplied temper; heat treatment and section size will move the numbers, so confirm with your mill certificate for critical parts. The summary table is followed by notes on why each value matters to a designer.

تُظهر مقاومة الشد والحدّ yielded strength حجم الحمل الذي يمكن للمكوّن تحمله، بينما يُبيّن الاستطالة مدى بقاء اللدونة اللازمة لامتصاص الأحمال الزائدة أو لاستيعاب عمليات التشكيل. أما الصلادة فهي مؤشر مفيد لمقاومة التآكل ولتوقع تآكل الأدوات أثناء التشغيل الآلي. وبجمع هذه القيم، يمكنك تحديد أبعاد المقاطع، واختيار عوامل الأمان، ووضع حدود الفحص بثقة.

Because PEEK 150G is a polymer, the strength numbers describe behaviour at room temperature and change markedly with heat and strain rate. Treat them as a starting point and validate with molded or machined coupons under your actual service conditions, especially where creep or repeated impact is expected.

الخصائص الفيزيائية والحرارية

Physical properties affect machining strategy as much as mechanical ones. Density drives mass and handling, thermal conductivity governs how heat leaves the cut, and the melting or softening point sets the ceiling for cutting speed and the type of coolant you can use. The table below summarizes the key values for PEEK 150G.

These values explain why PEEK 150G machines the way it does. Low thermal conductivity, for example, traps heat at the tool edge and pushes you toward sharper tools, lower depths of cut and aggressive coolant delivery. A low or high density changes how you fixture and balance a part. High strength-to-weight ratios, on the other hand, are exactly why designers keep specifying this material even when a cheaper alternative exists.

الخصائص الرئيسية

PEEK 150G earns its place in engineering designs because of a short list of characteristics that matter on the shop floor and in the field. Each one is explained below so you can judge fit against your requirement.

Higher stiffness than unfilled PEEK

Higher stiffness than unfilled peek In the context of PEEK 150G, this matters because it influences both the performance of the finished part and the way the raw stock must be processed, heat treated and machined to release its full potential.

Better creep resistance

Better creep resistance In the context of PEEK 150G, this matters because it influences both the performance of the finished part and the way the raw stock must be processed, heat treated and machined to release its full potential.

Lower cost per part

Lower cost per part In the context of PEEK 150G, this matters because it influences both the performance of the finished part and the way the raw stock must be processed, heat treated and machined to release its full potential.

Retains PEEK’s chemical and thermal resistance

Retains peek’s chemical and thermal resistance In the context of PEEK 150G, this matters because it influences both the performance of the finished part and the way the raw stock must be processed, heat treated and machined to release its full potential.

Together these traits make PEEK 150G a practical choice where performance, weight and manufacturability must all be satisfied at once. None of them is unique on its own, but the combination is what separates a specification-grade material from a commodity one.

التطبيقات الصناعية والهندسية

The real test of any material is where it is trusted in production. PEEK 150G appears across aerospace, automotive, energy and precision industries in the following roles, each chosen because the property profile matches the duty cycle:

Structural insulators

Rigid electrical and thermal parts.

When we produce structural insulators for this kind of application, we pay particular attention to the critical dimensions and surface condition, because that is what determines whether the part survives its service life. Our inspection reports document every key feature.

إرشادات التشغيل الآلي باستخدام الحاسوب (CNC)

Machining PEEK 150G successfully is about matching tooling, speed and coolant to its specific behaviour. The recommendations below reflect shop-proven practice for holding dimension, surface finish and tool life, and they are a starting point that our programmers refine for each geometry.

اختيار الأدوات

Diamond-coated or sharp carbide; glass is abrasive.

إلى جانب درجة المادة، تُعتبر هندسة الأداة مهمة أيضًا: فالزاوية الأمامية العالية تقلل من قوى القطع، والأخدود المصقول يساعد على تصريف الرقائق اللزجة، كما أن حامل الأداة الصلب يحد من الاهتزازات التي قد تفسد نوعية السطح. ونختار الهندسة المناسبة لكل عملية بدلاً من استخدام مثقاب نهائي واحد متعدد الاستخدامات.

معايير القطع

Milling 180-350 m/min, turning 80-200 m/min.

تفترض هذه النطاقات وجود آلة صلبة وقطعة مثبتة بإحكام. إذا ظهرت ظاهرة الاهتزاز (التشاتر)، فإن أول إجراء يجب اتخاذه هو تقصير طول المسبار وزيادة سرعة المغزل حتى الوصول إلى منطقة عمل مستقرة، وليس مجرد تقليل سرعة التغذية. تقوم ورشنا بتوثيق المعايير الفعّالة حسب المادة، بحيث تبدأ الأعمال المتكررة من نقطة موثوقة ومعروفة.

التحمل وتشطيب السطح

Hold +/-0.02 mm; anneal to stabilize dimensions.

تثبيت القطع وتجهيزها

Stable workholding is the quiet hero of precision machining. For PEEK 150G we favour full-contact soft jaws, vacuum or dedicated fixtures that constrain the part without distorting it, then measure the first piece before releasing the batch. This discipline is what lets us hold the tight tolerances the application demands.

Common challenges when cutting PEEK 150G: Abrasive fibers wear tools; use diamond coating, sharp edges, coolant, low depth.. A rigid setup, sharp edges and consistent coolant delivery resolve most of them, and our quality team verifies every critical dimension before shipment so the part that reaches your dock is the part on the drawing.

المعالجة الحرارية وتشطيب السطح

Anneal near 150 C after roughing to relieve stress.

After thermal treatment, PEEK 150G is usually finished by grinding, honing or light CNC cleanup to reach the final tolerance, because hardened material is too hard to cut economically. Surface treatments such as anodizing, plating, nitriding, black oxide or coating can then be added when wear, corrosion or appearance call for it. We coordinate heat treatment and finishing with machining so distortion is planned for, not discovered late.

How PEEK 150G Compares with Similar Materials

No material is chosen in isolation. The table below positions PEEK 150G against nearby alternatives so you can see where it wins and where a substitute might be better. The right choice is almost always a trade-off between cost, weight, strength and how easily the part can be made.

إذا كانت أولويتكم هي الحصول على أقل وزن ممكن، أو أعلى قوة، أو أسهل عملية تشغيل، فقد يكون الجار المناسب في هذا الجدول هو الخيار الأفضل. يمكن لمهندسينا إجراء دراسة سريعة للمفاضلة بناءً على الأحمال والأحجام الخاصة بكم، وغالباً ما يؤدي تعديل بسيط في التركيب أو حالة المعالجة إلى استبعاد الحاجة إلى عملية ثانوية مكلفة.
