When it comes to new product created by enterprises, choosing the right manufacturing technology plays an important role to make things go smoothly.
3D printing is based on adding materials layer by layer (additive manufacturing). To some extent we can say, CNC processing is the opposite service.
CNC is considered subtractive manufacturing because tools remove materials until they meet the demanded shape. Although both of them are suitable for similar materials, 3D printing services are usually a better choice if you need a small number of parts quickly at the lowest price. 3D printing also suitable for more difficult designs and materials. However, CNC is highly recommended for its accuracy, that is a good thing for mechanical parts.
Although there's some limitations in terms of some tools in CNC, the approach is also applicable to small and large projects. 3D printing has a thickness specified by the printer nozzle, and the layers are usually visible in the finished product. Because of the production area, 3D printing usually has a smaller maximum size.
As regarding to materials, CNC processing performs well in metal, while 3D printing is usually made of kinds of plastics. CNC is a reliable method if you want solid and reliable mechanical parts, but 3D printing does not have many geometric constraints.
In the two processes, CNC machine tools are the most labor-intensive. Engineers need to choose tools, speed and repositioning options, all these factors may affect the final product, including the required production time. The last piece may still need to be repaired. On the other hand, 3D printing starts quickly from the design file to the finished product.
After the printing is done, the product may need to be cleaned, polished or otherwise completed.
How to decide which process is the best?
So easy - CNC offers are ideal for 250-500 quantities that do not require complex shapes, while 3D printing is best suitable for more complex shapes, prototypes and small quantities. If an order exceeds 500pieces, other processes are best considered.
Rapid prototyping has many benefits. In addition to being your fast track to product-market fit, rapid prototyping can help you with all of the following:
1. Quick Iterations Generate Progress
Rapid prototyping uses short cycles to quickly improve the core design, and it's not unusual to see cycles [Open/Close]
as short as a few days or a week. In the earliest stages of low fidelity prototyping, the cycles could be even shorter than this.
In addition to improving the design quicker than other methodologies, the visible progress this provides helps to increase buy-in from the team and stakeholders at an early stage. By getting this early buy-in from stakeholders, projects that use Rapid Prototyping benefit from increased stakeholder feedback compared to other methodologies.
2. Focus on Improving Core Features
Unless the project is very small, there isn't time to prototype every single page, feature, or function. Instead, rapid prototyping forces the team to prioritize the small number of features that deliver the biggest impact for the project.
This focus ensures the time and resources are spent where they'll have the biggest impact and avoids the design phase getting bogged down by minor details. Used properly, rapid prototyping should conform to the Pareto Principle, covering the 20% of features that deliver 80% of the impact.
3. Focuses Design on End-User
With its focus on end-user testing, rapid prototyping emphasizes usability and customer experience from the beginning of the project. This early feedback helps to refine the design and reduces the likelihood of the development becoming delayed due to requests for significant changes.
This means projects using rapid prototyping often lead to results that are closer to the customer's initial intentions. This is especially true when compared to waterfall methods, which lack the opportunity for early end-user feedback.
Computer Numerical Control (CNC) refers to - manipulating traditional machines by the use of computer systems. CNC machining has become common as the use of computers has increased in industrial manufacturing processes. Conventional industrial equipment like centre lathes, routers, drills and millers are now operated through computers to achieve better control.
On the surface, it may seem like a simple computer is controlling the machine, but the unique software and control is what really sets the system apart in CNC machining.
Nowadays, CNC machining is found in many industries to aid production as it streamlines the manufacturing process. Some major benefits of CNC machining in manufacturing are:
1. Greater Efficiency
One reason for using CNC machining for production is efficiency. Since computers are used to control machines, it means that all major operations of production can be automated to increase speed and quality of manufacturing. On the other hand, if CNC machine is not used, a technician will have to drill which would take more time.
CNC machines do not have to be switched off, unless maintenance is needed, meaning that the production can go on without any break. Human beings get tired and require rest which means that production must halt. Machines controlled through computers don't fatigue and do not need break, thus the process of production is streamlined. Such efficiency can never be achieved through a manual process.
2. More Accuracy
Another reason CNC machining is beneficial for manufacturing is its accuracy. CNC machines are programmable and each and every detail of the production process can be fed into the machine. By using CNC machines, identical parts can made with the highest accuracy levels. Programming the specification and designs into the machine leaves no room for mistake or error.
Reducing errors from the manufacturing process eliminates unnecessary waste. CNC machines can manufacture ideal parts to meet requirements of clients. High accuracy level also makes it hard for others to duplicate and steal the design of products. CNC machines allow producing products which otherwise may be impossible to produce through manual processes as human beings are limited in their capabilities.
For fabrication, CNC machines are very important. Several operations are involved in fabrication such as welding sheets of metal, shearing, punching holes and flame cutting which can be done safely by using CNC machines. Large machines can be fabricated through CNC according to any desired specification. CNC machines are reprogrammable and flexible which makes them an ideal choice for fabrication.
CNC machining is absolutely essential for manufacturing and it is important that the machine keeps running otherwise major loss would be suffered. But like any other machine, CNC machines also wear and tear and if some parts of a CNC machine get damaged, it can be hard to find a replacement.
This is why we, at JF Berns, provide best quality CNC accessories so that you can fix your CNC machine in case of any damage and keep the production running continuously.
Sometimes you need a prototype or low-volume injection mold rather than a full production mold.
Maybe you're just at the point of needing some prototype plastic parts to test for form, fit and function.
Or maybe you need a bridge tool to ramp up to full production.
At VOWIN we're very good at producing prototype molds, and we can make them very quickly and [Open/Close]
at low cost.Our prototype molds carry a warranty of 10,000 cycles, so they're ideal for low-volume plastic parts,
and they're less expensive. (We also offer production molds, which carry a lifetime warranty).
We manufacture our prototype / low-volume molds out of S50C or P20 soft tool steel.
This not only reduces cost, but also makes it possible to modify the mold if you decide to change your design once you've tried out your prototype parts. Mold makers who use aluminum molds, as some of our competitors do, cannot easily modify their molds, if at all.
Top 3 Ways why You Can Use Prototyping Molding to save Your time and cost :
1: Aluminum tooling --- Save the mould material cost,
2: old mould base tooling ---Save our make time.
3: same new mould base different core Tooling.---- we can repeat use the mould base . so You can be better than ordinary mould province 60%.
This is a very good question to start with. Before we can start to formulate our own conclusions, let's go ahead and find out what plastic injection molding and die casting is first. These are the difference between mould and die.
What is Injection Molding?
It is considered to be one of the most popular manufacturing processes today. It is widely used by custom [Open/Close]
belt buckle manufacturers. Depending on what is needed, raw materials can be made of metal, glass, confections, or elastomers. But the most popular raw material is plastic.
How Are Products Made with Injection Molding?
First, design and plans must be finalized. After everything is ready, raw material like duraflex material will be melted in a big barrel. After melting, it is injected into a mold that is usually made of strong metal. After taking the shape of the mold, it is allowed to cool and ejected from the machine. These are the injection moulding process parameters.
Some products manufactured under this method are automotive parts, toys, kitchen utensils, combs, bottles, appliances, educational supplies, strap buckles, and a whole lot more.
The Injection Moulding Advantages
This manufacturing process has a lot of advantages. First, it is very cost effective because little or no waste is produced. Second, it is very eco-friendly due to the first reason. And third, it produces high quality products. With all of this in mind, can you even imagine a life without injection molded plastic?
What is Die Casting?
Now that you are already familiar with injection molding, it will be easy for you to understand what die casting is. Unlike injection molding, die casting only engineers various metal parts or products made of metal.
How Are Products Made with Die Casting?
The process is also similar to injection molding. Raw materials made of metal is melted under extreme but exact temperature, forced into durable steel molds and allowed to cool before taken off the machines.
Are you a toy car collector? Your toys probably are made through the die cast system. Steel pipes, car parts, electronics, golf equipment, and faucets are just some of the products made through it as well.
The Die Casting Advantages
It has numerous advantages. First, the system can be done in an automatic fashion. Second, the molds can be used over and over again due to its durability. Third, the products made through this are more durable and has a longer service life. And fourth, it is economical too!
So Which is Better?
There may be a difference between mould and pattern in casting but the answer totally depends on what you need. If you need products that are very durable and can withstand extreme temperature and has magnificent electrical properties, die casting should be your choice but if you need plastic products with highly complex designs but are durable for everyday life, then injection molding maybe it.
You may also consider the types of moulding available for each system before you can finally choose the right one for you.
