How To Use Design For Manufacturing For Product Development

 

Designers tend to speed up the manufacturing process via cheaper means. Hence, design manufacturing entails all these aspects. Also, DFM aids in producing goods that are of high quality. Optimization of any product design is crucial in any process. At Creatingway, we use DFM to perfect your projects. Such an improvement increases lifespan and works efficiency. Below are some critical aspects of DFM and tips on choosing the method.

What’s The Design For Manufacturing (DFM)?

DFM is a procedure that aids in designing products more easily. It offers efficient production, cost-effectiveness, and quality idealness. While creating a product, we consider the manufacturing method. Other considering traits include; shapes, dimensions, material, and labor cost. Hence, Different product development and rapid prototyping process that uses DFM manufacturing include;

• 3D printing
• Vacuum Casting
• CNC machining
• Rapid Injection Molding

Design Manufacturing Process for Different Rapid Prototyping Process

In the DFM process, we use various rapid prototyping methods to achieve production, At Creatingway, we usually suggest to customers to make 3D printing, CNC machining, or Vacuum casting process, whatever, we will offer our customers the best reasonable ones, so you can make new projects to marketing as soon as possible.

3D Printing

3D printing requires technology that DFM is good. For any successful 3D printed product, consider the time it takes to design it. By doing so, the workpiece has adequate time to adapt to the specific features. Also, manufacturing the item is more flexible and easy. Streaming lining enables the minimization of waste and saves on money and time. Below are tips to consider while using DFM in 3D printing;

• Involve fewer moving parts ensuring workpieces will last longer.
• Note the types of materials in use. Most preferably, choose a more durable material to increase the lifespan of a product.
• Easy replacement of removable parts by the manufacturer
• Right proportions of 3D printing dimensions. Such a trait reduces material cost, increasing products’ quality.

CNC Machining

CNC machining is a complex method that requires DFM’s help to simplify it. So, manufacturers can tune parts to be more manufacturable. Designers ensure no alteration of designs via DFM. Under such a process, drawings and CNC prototyping hinder manufacturing. Also, we can combine factors of a product design more efficiently. Some elements include; parts design, workpiece layout, and heat transfer analysis. The absence of DFM delays production and increases the risk of unwanted errors.

DFM in Injection Molding and Vacuum Casting

A major difference is injection molding has a higher molded-in-stress than vacuum casting. For vacuum casting, we pour liquid into a mold where it cures. As for injecting molding, we inject molten silicon into an already made cavity. Below are some differential considerations with DFM;

• The cost of creating an injection mold is higher than vacuum casting. Since the molds of vacuum take days but take longer in injection molding.
• Wall thickness must be precise in injection molding but less strict in vacuum casting.
• In terms of the complexity of the model, vacuum is much simpler. Unlike injection molding, there is only a one-piece model to the machine.

What Are The Principles of Design for Manufacturing?

• Process

With the right manufacturing method, proper product development is guaranteed. While choosing the mode of production, we consider various factors. Some include; volume, surface finish, cost production, tolerance, and post-processing wants. Later, select the most appropriate method according to your wants.

• Material

Before any process, the choice of material used is vital. We look at the grading and form in which it is in. such considerations affect the final product outcome. We look at opacity, strength, durability, and machinability factors, Also, we need to discuss with customers for reasonable, further consider product purpose, mechanical property, product appearance, and more factors.

• Design

Any idea contributes to the making of a workpiece. Also, the cost of the product is crucial due to competing demands. In the early design phases, use DFM tools to predict the outcome. Also, the tools help in the cost reduction of products.

• Testing

In any DFM activities, always consider testing the requirements needed. Such a procedure helps in preventing any future complications. Furthermore, the reduction of problems boosts workpiece efficiency and lifespan as well.

• The Service of Environment

Environmental factors contribute to the traits which the workpiece will entail. Also, in some instances, it determines the use to which the equipment is subjected. Cases like hot or cold conditions will make items differ according to the intended want.

Importance of Design For Manufacturing (DFM)

• Sustainable Products

It ensures the production of material by using workable materials. By doing so, waste reduction is observable and saves money via reduced labor costs. Manufacturing operations won’t be as complicated compared to other machining processes. All of these suits the wants of consumers as they are sustainable.

• Cost-Effectiveness

With the use of the DFM process, products become efficient and cost-effective. A manufacturable material enables one to produce a product at a reasonable cost. Hence, as the product becomes more affordable, the more the consumers opt to buy it.

• Increases Quality of a Product

There are ways in which you can improve the quality of a workpiece. One of them is by using DFM in surface finishing. So, we save time and money as there are fewer mistakes in production. Later, the efficiency of the item increases greatly.

What’s The DFM Analysis Report?

The report on DFM bridges between the mold manufacturer and product developer. Most industries prefer the method as it improves efficiency. As a mold maker, having a DFM report in any mold-making project is vital. In doing so, you can foresee the potential risks during the manufacturing process.

• The Design Thickness

Avoiding uneven wall thickness is very crucial. The rib thickness is nearly 60% of the wall thickness. Thin-walled areas are usually avoided at any cost. Furthermore, the thin-walled thickness also can be avoided shrinkage of the product surface.

• Resin Used

Some raw materials include; Nylon, HIPS, PC, ABS glass, and fiber. The pricing and suitability are different between these materials. Also, the shrinkage rate varies, and its a major factor in tolerance and measurement precision.

• Parting Line

In any mold design, it’s vital to summarize the project design. Any other mechanical structures used like; lifters or sliders are also included. Ensure that the parting line is acceptable. Also, to make sure the appearance aesthetic is best.

• Gating Way

On surface finishing, gate locating is highly recommended. Thus, the type of gate gauges how product production takes place. Also, to make our production smooth enough, and improve the production efficiency. As usual, we always consider auto-fall off during the production, so we can reduce the manual work to operation.

• Engraving and Finishing

There are many forms of the finishing process. Defining where engraving takes part, and the content it entails is essential.

In conclusion, it’s crucial to consider DFM as you start a process. At Creatingway, we use DFM to perfect consumer projects. Also, the years of expertise enable us to offer advice concerning the procedure. Kindly consider Creatingway while dealing with projects that undergo the DFM process.
