Unlocking the Potential of CNC Machined Plastic Parts
Types of Plastic Used in CNC Machining
Not all plastics can be CNC machined. However, one thing to note is that the more rigid a plastic is, then, the easier the better machinability it has. On the contrary, the softer and more flexible the plastic, the less suitable they are for machining.
In the world of machining, there are about a few different types of plastics that respond well to machining. These plastics include, but are not limited to:
- بولي كربونات أو الكمبيوتر الشخصي
- Acrylonitrile Butadiene Styrene or نظام ABS
- نايلون 66
- Polyetheretherketone or نظرة خاطفة
- Polytetrafluoroethylene or مادة البولي تترافلورو إيثيلين
- البولي إيثيلين ذو الوزن الجزيئي العالي جدًا (UMHW)
- و الكثير غيرهم
The Most Suitable Plastics for CNC Machining
Currently, the types of plastic that hold the trophy for the best Machinable plastics are ACETAL, PVC, و نظرة خاطفةدعونا نناقش الأسباب التي تجعلهم يعتبرون الأفضل عندما يتعلق الأمر بالتصنيع، وكيف أصبحوا كذلك.
الأسيتال
تُعد مادة الأسيتال من المواد الرائدة في تصنيع البلاستيك نظرًا لحقيقة أنها تتمتع بمستويات عالية من القوة مع احتكاك منخفض. بالإضافة إلى ذلك، تتميز أيضًا بامتصاص منخفض للرطوبة ومستويات عالية من الاستقرار البعدي.
بولي فينيل كلوريد أو PVC
Polyvinyl Chloride or PVC, for short, is another plastic type that’s excellent when it comes to machining and fabrication. The reasons why would be because of its multiple beneficial properties, which include water, flame, and corrosion resistance; not to mention that it also has high levels of toughness, strength, and impact resistance!
بولي إيثير إيثير كيتون أو بيك
أخيرًا وليس آخرًا، هناك PEEK، الآن، مقارنة بالاثنين الأولين، يعتبر PEEK أو بولي إيثير كيتون بلاستيكًا ممتازًا يمكن تصنيعه بسبب قدرته العالية على التكرار ومستويات التسامح الضيقة ونقاط الانصهار العالية والدقة العالية.
ملحوظة: حتى لو كانت هذه هي أفضل أنواع البلاستيك وأكثرها فعالية في التصنيع حسب الطلب، فهذا لا يعني أنك مقيد بهذه الأنواع. لا توجد قاعدة مكتوبة تنص على أنه لا يمكنك استخدام أنواع أخرى من البلاستيك لإنتاج أو تصنيع أجزاء الآلات.
CNC Machining Processes Commonly Employed for Plastic Parts
In manufacturing accurate plastic components, Computer Numerical Control is an important factor. ال الطحن technique, which is a flexible tool using a rotating cutter, has incredible success in generating detailed patterns. Drilling and تحول are effective for cylindrical figures which includes creating holes that require high speeding. The control of the production process, when larger cutting tools are used for sculpting and trimming plastic peripherals is best achieved by applying routing methodology.
On the other hand, albeit not an exemplary machining procedure, الطباعة ثلاثية الأبعاد is creditable for development of plastic parts depress section at a time and also quick prototyping as well as used to underwrite complex geometries.
Secondly, selecting a certain CNC machining process depends on the needs of each project that uses various qualities; every method has benefits related to accuracy precision cutting material and flexibility in shape size.
Finishing Options for CNC Plastic Parts
There are several finishing options available for CNC-produced plastic parts depending on desired aesthetics and functionality, cost considerations or both.’ Among the commonly preferred possibilities are sand grinding and polishing which gives it a glossy finish and makes its surface flat. Painting creates a more aesthetically pleasing appearance, but case compatibility with the type of plastic is essential. Anodizing, typically for metallic materials, is suitable to some plastics with the aim of producing a desirable coating that resists corrosion and in case it offers exceptional durability.
Dyeing is a technique which colors without changing the way something feels, that works well for products which are clear. While powder coating is more prevalent with metals, it can be a good option for some plastics because the finish created by this application procedure provides excellent durability and evenness. However, laser etching can be used for more detailed marking. Take into account the materials under consideration, actual use and try to test prototypes for compatibility issues evaluation as well as final outcomes showing.
إيجابيات أجزاء البلاستيك المصنعة حسب الطلب باستخدام الحاسب الآلي
في التصنيع باستخدام الحاسب الآلي وحده، سوف تكون قادرًا على العثور على فوائد ومزايا متعددة - ماذا لو قمنا بالجمع بين التصنيع باستخدام الحاسب الآلي والبلاستيك الحراري؟
هذه هي إيجابيات ومزايا استخدام آلات التصنيع باستخدام الحاسب الآلي البلاستيكية لإنتاج الأجزاء التي تحتاجها:
التحول السريع
Plastic CNC products are the best when it comes to prototyping because it wouldn’t take you a big number of hours for the prototype to be made. All that’s needed is the plastic material, as well as the design of the product to be manufactured, and the prototype will be made.
إن النماذج الأولية الأسرع تعني دائمًا سرعة تسليم الأجزاء أو المكونات المطلوبة.
التسامحات الأكثر صرامة
Another benefit of CNC plastic machined parts is the fact that they can easily accommodate tighter tolerance requirements. So, if you are in an industry that requires more accurate and precise jobs, you won’t have a problem, not to mention that these can be prototyped faster and easier!
مقاومة أفضل للتآكل
أخيرًا وليس آخرًا، فإن هذه المنتجات تتمتع بفوائد ومزايا مقارنة بالأجزاء المعدنية – وذلك ببساطة لأنها مصنوعة من البلاستيك. وبالمقارنة بالمعدن، يمكن أن تكون قوية ومرنة ومتينة ومقاومة أيضًا!
تحديات قطع البلاستيك المصنعة حسب الطلب باستخدام الحاسب الآلي
وإذا كنت تعتقد أن الأجزاء البلاستيكية المخصصة المصنوعة باستخدام الحاسب الآلي تقدم دائمًا ألوانًا قوس قزح وفراشات، فهذا ليس صحيحًا. في الواقع، هناك بضعة اعتبارات يجب مراعاتها قبل اختيار الأجزاء البلاستيكية المخصصة المصنوعة باستخدام الحاسب الآلي - وتشمل هذه، على سبيل المثال لا الحصر:
التشويه والتشكيل
The most common challenge or drawback to it is that warping and tooling of the components made are especially common. This is more prevalent when the part of the component only requires a thin piece of plastic.
غالية الثمن نسبيا
Another drawback is the fact that CNC machining is quite expensive and costlier than traditional production methods. The use of high-quality CNC machines, and of course, expensive types of resistant plastic is what makes it heftier.
Compare Plastic Injection Molding With CNC Plastic Machining
Plastic Injection Molding and CNC Plastic Machining are two separate processes that possess different benefits. Plastic Injection Molding produces molded plastic components from plastic pellets that are melted and injected into molds, allowing for high-volume production with complex shapes. Though upfront capital costs and mold creating time may be substantial, the process is cost-effective with greater quantities. It is good at applications requiring high precision, close tolerances and complicated designs.
The other method, CNC Plastic Machining, is the process of removing material from solid blocks using precise tools. Ideal for small to moderate quantities and less complex designs it provides shorter setup times with lower start-up costs than injection molding. Thus, CNC Plastic Machining is valuable especially for prototypes, smaller batches and projects with short horizons. While it may lead to greater waste, particularly for complicated forms, its flexibility and shorter turnaround times make it a favoured option in some cases.
In both processes, material selection plays an important role; Plastic Injection Molding includes a wide range of materials while CNC Rubber Machining has limited options. The other important considerations are precision and tolerance, wherein both methods produce high-precision that can be used for a wide range of applications. The employment of Plastic Injection Molding and CNC Plastic Machining depends on the production volume, part complexity, material needs, money available. Every approach has particular strengths, and the choice should best match what a project requires.
