How To Compared CNC Machined Parts And Molded Parts
Recently, retailers can easily find machined parts in most parts of the world. CNC machining has enabled accessibility as it suits both metal and plastics machining. This trait eases the burden of prototyping in factories compared to molded ones.
At Creatingway, we can quickly fabricate machined parts and afford them without tooling. Also, prototypes and machined parts get provided at fair pricing. Our years of experience have enabled us to render advice in this sector.
What Are Machined Parts?
We mainly use the machined parts in mass production and rapid prototyping. During manufacturing, machined parts may be mistaken for molded parts. Other parts, such as; casting, extruded, and 3D printed ones, also get contrasted. Parts made via subtractive cutting machines are known as machined parts. The cutting process may involve;
- CNC mills
- CNC lathes
- Grinders
- EDM
- Manual mills
- Manual lathes
The major difference comes in a while looking at the method of production. A machined part is an item that comes from one of those techniques, but the finishing process is machining. Also, we may refer to machined parts as CNC machined parts or CNC parts.
Below Are Reasons Why You Should Choose Machined Parts Over-molded Ones
Plausible Prototyping Solution
Large companies can afford to order injection mold prototypes. The reason is that the cost of tooling makes prototyping expensive. CNC parts are affordable and suitable for prototypes. We can easily make the parts as one-offs. Machining is much quicker than molding. R&D departments can easily replicate several versions of a part. Also, testing and assessment of the replica get done before continuing with the production. Companies may order machined parts in various metal alloys to see which performs the best under tested conditions.
Helps You Stay Ahead of Competition
Retailers use CNC machined parts for various purposes. In our current century, competition is all over the industries. To remain at the top, one should use the best machining tools. Machining provides efficiency and accuracy, reducing the time spent making a material. Also, the products produced are of high quality, increasing your project’s lifespan. Hence, to stay ahead of your competitors, machining is the best Industrial method.
No Minimum Order Quantity
You require no minimum order quantity to purchase CNC parts. However, molded parts require the fabrication of metal tooling. Such a process takes a long period and costs highly. As for CNC machined parts, we obtain them by cutting them from a blank workpiece. Such a method is effective as it costs less to order very small quantities. Hence, machining typically offers products of high quality with no MOQ. Small companies use the process to run small production and prototyping.
Alterations
We make CNC machined parts from a digital CAD file. Such an application enables digital design changes suiting the desired fabrication. Engineers see it as applicable during prototyping and R&D processes. The easiness of fractionally adjusted machined parts or replicating parts is evident. Also, machining offers any possible waste reduction since the process rarely makes defective parts. Hence, such a trait is a significant advantage for machined parts over-molded parts.
Quality
The end product of machined parts is of a very high standard. Also, potential customers may specify the tolerance needed to meet their desired project. Operators may take extra time to improve individual features and tight-tolerance parts. Moldings produced lose the definition of earlier units towards the end of their lifespan. Finally, the machining process eradicates surface quality problems associated with molding. The linking issues may be; flow lines, jetting, and flash at the parting line.
Design Freedom
CNC machined parts may differ in shape and size. Such a trait arises from the absence of exposure to extreme molding design restrictions. Molding design constraints are like; tapering and thin walls. We may obtain thick and robust CNC parts with their features delicate and detailed. Though, CNC parts have some limitations in deep channels and internal sections. Even with such limits, machining is the most geometrically flexible process in the manufacturing industry. Molded parts, however, must be thin-walled to conform to a more precise design.
Increased Accuracy
Manufacturing industries require metals that withstand manual turning and milling processes. CNC parts render perfect aspects suiting industries’ such as high accuracy. Molded parts lack the unique characteristic making them less effective.
What’s The Advantage Of The CNC Machining Process?
Compared to parts made via molding, CNC parts get fabricated faster. Such a trait is evident due to the lack of labor-intensive tooling. Also, the machining method itself is highly effective. Some faster machining centers equip themselves with linear guide rails. They can achieve rapid rates reaching around 4000 cm/min. Such speeds increase productivity rates.
Also, the CNC machining process makes our product development and design is very flexible and low cost, so our designer and engineer team can make their design and prototype very quickly for testing and verification, then present customers. If so, the whole development time will be reduced too much. As usual, the delivery time for the CNC machining part is 1-7 days, but our mold parts are around 15-20 days, and even some complex parts will be longer.
In conclusion, machined parts are of greater use compared to molded materials. At Creatingway, we use the machining process to obtain desirable results. CNC parts produced are of high quality and very efficient. Our years of expertise enable us to weed out the pros and cons that may create an impact on your project.
