Design for manufacturing (DFM) is a process that entails designing components, parts, or products to optimize the manufacturing process used to produce them. Ultimately, DFM helps maximize the efficiency and cost-effectiveness of manufacturing processes through optimized product designs that address any potential discrepancies or mistakes. People may also refer to DFM as design for manufacturing and assembly (DFMA).
(Click to Expand)
There are five main principles behind the DFM process that help optimize designs to prepare them for manufacturing. These principles are as follows:
The first step of the DFM process is to select the appropriate manufacturing process for the component or product. For example, thermoforming may be a better process for low-volume parts compared to less efficient injection molding processes.
The next aspect of the DFM process is the design, which involves drawing the product or part based on the principles specific to the selected manufacturing process.
After the drawings are completed, it’s time to select the right materials for the design. Certain contributing factors to material selection may include mechanical, thermal, optical, electrical, and fire-retardant properties, along with color.
Parts or products must be designed to hold up in the environments in which they’ll be used. Otherwise, they won’t be able to function properly, regardless of the quality of the design.
Products and components are required to maintain compliance with quality and safety standards. These standards could include industry standards along with company or third-party standards. It’s also important for manufacturers to have ISO certification.
There are several key benefits of using DFM processes to design products before manufacturing. These include:

Welding is the process of joining two surfaces together by applying heat, pressure, or a combination of both. The types of welds used to create the weld joint can be categorized into various types, which are largely defined by their cross-sectional shape and the methods used to produce them. Understanding the various weld types and their distinct characteristics and advantages is the first step toward achieving a reliable, high-quality weld that meets your application-specific requirements.
Here, we cover some of the most common weld types, their key benefits, and the applications for which they are best suited. To learn more about Chapter 2’s welding capabilities, visit our capabilities page.
A fillet weld joins two surfaces perpendicularly, forming an approximate right angle between them. This style of weld can be further categorized into the following subtypes:
The versatility and low cost of fillet welds have made them one of the most widely-used joints in the welding industry. Typical applications include:
Groove welds allow parts to be joined in the same plane by depositing welding beads in a groove between them. The basic types of groove welds include:
Compared with other forms of welding, the groove welding process is generally more time-consuming, harder to perform, and typically requires special beveling on one or both surfaces being joined. However, it creates an easy-to-inspect, high-strength weld and offers good distortion control. Common applications of groove welds include:
Surfacing is a welding process in which the weld is applied to the surface rather than the joint to achieve certain properties or dimensions. This is accomplished by depositing one or more strings of weave beads onto an unbroken surface. The most common types of surfacing welds include:
Surfacing welds are commonly used to add a wear-resistant layer of metal to an object to strengthen its surface or rebuild worn areas. In these cases, a metal with a greater wear resistance than the base metal is used to perform the welding. This technique is one of the most cost-effective methods for protecting and prolonging the life of equipment and tools used in aggressive, high-wear applications. Surface welding can also be used in conjunction with square butt joints to enhance the quality of the final weld.
Plug welds are circular welds used to fasten two surfaces together through a small hole in one of the surfaces. In automotive applications, plug welds are commonly used in place of spot welds when there is insufficient space to accommodate spot welding equipment. The resulting weld is often stronger than a spot weld. Similarly, plug welds can be used to refill damaged holes in expensive aerospace components, returning them to a like-new state and saving companies on MRO costs.
Other applications include:
With slot welds, one surface is joined to another through an elongated hole. The difference between plug and slot welds is that the plug weld’s shape is characterized by its diameter, whereas the slot weld’s shape is characterized by both diameter and length. Depending on the part’s specifications, one end of the hole may be open, or the hole can be partially or completely filled with weld material.
Slot welds are beneficial when the part’s design requires an overlapping between two surfaces. Specific uses of slot welds include:
Flash welding is a method of resistance welding that eliminates the need for filler metals. During the flash welding process, a current is applied to create a resistance between the two surfaces to be joined. When the two surfaces come together at small contact points, the current flows and melts the material.
The melted material then exits the joint in a spray of molten particles, which creates the distinctive flashing action. Oxides and other contaminants are eliminated from the interface while a heat-softened zone is formed at the ends of the two surfaces. When enough material has melted, a force is then applied to join the surfaces. This facilitates the creation of a butt weld with no residual melted material in the joint.
The flash welding process is fast, economical, and capable of fusing dissimilar metals with different melting points. Flash welds are often used for:
Seam welds allow materials to be overlapped and joined along a continuous seam. This type of weld can be created using two methods:
Benefits of seam welding include:
Spot welding is a form of resistance welding used to merge two or more pieces of sheet metal without the use of filler material. This is achieved by concentrating an electrical current into small, precisely-spaced spots between the adjoined surfaces. Shaped copper alloy electrodes are used to convey the electrical current through the sheet metal pieces at the predetermined locations. Once the material is melted, the current is removed and pressure is maintained while the molten material hardens to create the spot weld.
Spot welds are relatively easy and inexpensive to create, making them a popular weld choice in several key industries, including:
Upset welding is a form of resistance welding that produces fusion concurrently across an area of adjoining surfaces, or progressively along a joint, using a combination of heat and pressure. Pressure is applied prior to and during the heating process, and heat is created by the electrical resistance occurring at the points of contact between the surfaces. Upset welds are commonly used in the fabrication of wire rings, burner rings, wheel rims, and other circular components with small cross-sectional areas.
The upset welding process delivers several distinct benefits, including:
Choosing the appropriate weld type for a given welding application is critical to the performance, reliability, and safety of the final welded component.

What a beautiful day to do a beautiful deed! Some of the Chapter 2 Crew made their way to Ronald McDonald House Charities of Madison to drop off $500 worth of gift cards for surrounding restaurants that will be given to the families staying at the house while their children are being treated at the Children’s Hospital. It’s a small gesture we hope can bring a little light to a family’s day while they endure some of their toughest moments. (Pictured with Ronald himself- Kali Garman & Kyle Johnston, Co-Owners of Chapter 2, Inc.)
Also donated in September was $500 to the Meal Program offered through The Ronald McDonald House. Due to COVID-19, in-person volunteering has been put on pause, but Chapter 2 hopes this donation can continue to provide warm meals to the families staying there. When volunteering resumes we hope to be able to help prepare these meals in person.
Chapter 2, Inc. is very excited to help the Lake Mills EMS purchase their first nitrous oxide tank to be used on their ambulances. The nitrous is used for immediate pain relief in place of opioids. If opioids are used in transit to the hospital, the patient cannot receive the necessary medical attention until the opioids have left their system. So with the use of the nitrous oxide patients can be treated right away. This is an exciting innovative stride used in the EMS industry and Chapter 2 is very happy to have been able to supply the funds needed to purchase the first tank.
Chapter 2 is excited about their WIMOTY Award nomination and cant wait to attend the banquet on Feb 20th, 2020 among many other great manufacturers in the state. Manufacturing is an important industry in Wisconsin and this event is a great opportunity for manufacturers to get together and celebrate their successes and growth.
Chapter 2 would like to send a special Congratulations to Todd Schmidt, maintenance technician, on 25 years with the company! Todd has been a vital asset to the company’s successes, which includes fixing just about everything within the shop at least once and has never complained about the things he’s had to fix twice. Chapter 2 hosted a dinner for Todd’s family, friends, and co-workers at Milford Hills Hunt Club. During the evening Tim Johnston, CEO, gave a speech reminiscing on the past 25 years and Todd spoke about enjoying coming to work everyday and digging in to problems that arise and finding solutions.
Chapter 2 has purchased their 2nd FANUC Robot paired with two new Doosan turning machines to add to their ever growing capacity! The robot tending operations aid in increased efficiencies and improve upon repeat-ability.
Some of the Chapter 2 Crew participated in the Run From the Cops event sponsored by the Watertown WI Police Department on 9/29/19. All proceeds of the run/walk go directly towards assisting victims of domestic and/or sexual abuse, and also towards creating awareness on this sensitive issue. A special congratulations to Chapter 2 employee, Hamilton Monroy for taking 1st place in his age group for the 10K race!
