PRODUCT DEVELOPMENT(R&D)

The process of mechanical product design typically involves the following steps:

1. Conceptualization: This is the earliest stage of the design process, where product designers identify the need for a new product or a redesign of an existing one. At this stage, the design team may gather market research data, identify user needs, and brainstorm creative ideas for the product design.

2. Engineering analysis: Once a product concept has been developed, engineers evaluate the feasibility of the design. Critical assessments such as stress analysis, finite element analysis, and modeling may be conducted to determine if the product will function correctly.

3. Design Specification: All design requirements for the product are defined at this point. It is critical to detail features such as size, shapes, materials, etc.

4. Design Calculations: Mathematical formulas and calculations are used to determine the strength, power, dimensions, and properties of parts to keep the intended specifications in consideration.

5. Prototyping: Designers create model assemblies or physicals prototypes with components to assess in reality what looks theoretically approved.

6. Testing: Fully-fledged project testing ensures that various products meet all requirements. For example, aesthetic assessment, usability, efficiency and performance.

7. Refining: After the prototype has been tested, engineers refine the product to improve its usability, durability, and safety features.

8. Production: Once the finished product design is authorized after correction as well as editing, manufacturers bring it in mass production to be delivered to customers.

DFX

Design for X (DfX) is a general phrase that refers to designing products with specific objectives in mind. These objectives are focused on various aspects, which are mutually beneficial to producing simpler and more efficient product designs. Some of those aspects may include:

1. Design for Manufacturing (DfM): The purpose of DfM is to produce goods in a manner that is low cost, high efficiency and rapid production. By considering manufacturability early in the design process, design teams can improve quality and reduce waste throughout the manufacturing process.

2. Design for Assembly (DfA): DfA focuses on the aspects that enable expert assembly with a low cost and efficient speed. It helps to simplify product assembly, reduce assembly time, and associated costs by designing the product, keeping in mind its assembly requirements.

3. Design for Serviceability (DfS): DfS focuses on regular pro-active maintenance as well as repairs. Factors like enabling easy accessibility to defective parts in the repair work goes into designing for serviceability.

4. Design for Test (DfT): DfT is designed to simplify testing effectiveness, enhances system quality, and fast identification of the defects. The aim is to reduce cost while ensuring quality-inducing accessible testing structures.

5. Design for Safety (DfSI): DfSI involves risk management and product safety design to avoid hazards that could harm the users, property, or workplace during product use.

6. Design for Environment (DfE): DfE is a key consideration for companies. This aims to produce sustainable products that minimize the environmental impact, from issues such as carbon footprint, water contamination to waste management. DfX methodologies will improve the user experience by providing cost savings, diminished time to value, and superior product quality and requires some costs; however, investing in the designing for X approach will reap economical and business rewards over time.

CNC MACHINING

What is cnc technology and how does it work?
Different types of machining processes are an indispensable tool in today’s industrial environment. Improvements in this area allow for increased efficiency and reduced production costs. And CNC technology has played an important role in its development.
A computer numerical control unit (commonly known as a CNC) is a system that allows the position of a physical element to be controlled at any time.
In machining processes, CNC is used to control machines such as CNC lathes or CNC milling machines and thus create fully customized follow-up products for the end customer.
What is CNC Machining?
This process involves designing a program with a set of commands added to determine the position and rotation of the tool in a sequential manner. In this way, its exact position and travel speed can be checked against the material used to manufacture the required parts.
Manufacturing process by CNC technology
The first stage of the process involves the precise design of the part to be manufactured using a CNC machine. It is usually done with a CAD computer aided drawing program.
Once the part has been designed, the instructions needed to produce the output part are encoded into the machine tool. These instructions are what make up the CNC program, written in a possible and standardized language engine. When using the code, all steps followed by the tool must be specified sequentially and in detail, e.g. precise positioning, direction and feedrate, depth, starting or pausing steps tools. job. tools, etc.
The CAM (Computer-Aided Manufacturing) program combined with the CAD-aided drawing program allows the automatic creation of CNC programs that will be coded into modularized machine tool control.
In recent years, Suno has proven itself to be a leader in CNC-based processes.
We use the latest technology in CNC machines, such as high-quality CNC lathes, which provides greater precision in the machining process and reduces production time.

Aluminum Die casting

Aluminum die casting is the method of choice for many automotive, industrial, and telecommunications products. It’s also often used to produce electrical, hydraulic, and lighting components.
What is Aluminum Die Casting? The Process Explained
Aluminum die casting is a metal-forming process that allows for the creation of complex aluminum parts. Ingots of aluminum alloy are heated to very high temperatures until they are entirely molten.
The liquid aluminum is injected under high pressure into the cavity of a steel die, also known as a mold — you can see an example of a mold for automotive parts above. The die is made up of two halves, and after the molten aluminum has solidified, they are separated to reveal the cast aluminum part.
The resulting aluminum product is precisely formed with a smooth surface and often requires minimal or no machining processes. Given that steel dies are used, the process can be repeated many times using the same mold before it deteriorates, making aluminum die casting ideal for the high-volume production of aluminum parts.
The Advantages of Aluminum Die Casting
Die casting aluminum offers several advantages over other metal-forming processes that might make it the appropriate choice to create your aluminum parts.
One of the most noteworthy is the ability to produce very complex shapes that neither extrusion nor machining can effectively create. A perfect example of this is the production of complex automotive parts, like transmissions and engine blocks. Other processes cannot consistently achieve the complexity and tight tolerances required for these products.
The Top Considerations During Part Design
A few considerations have to be taken into ac when designing the part to be cast.
Firstly, the mold must be designed to separate and allow the solidified aluminum part to come out. The line that marks where the two halves of the mold come apart is referred to as a parting line, and you have to consider it in the early stages of die design.
Another important consideration is the location of injection points. The die can be designed with several injection points in cases when the molten metal would otherwise solidify before reaching every crevice in the die. This can also help if cavities are included in the design; you can surround them with aluminum and still have the part come off when the mold is separated.
You must also consider the thickness of the part’s walls. There are usually no guidelines for a minimum wall thickness, thanks to recent technology developments, but having walls with consistent thickness is often preferred.
Options for Machining and Finishing
Die cast aluminum parts often require minimal machining, and several options are available for surface finishing. Die casting has a very good surface finish by casting standards but can still have imperfections, like metal seams where the mold halves meet. A rough surface or other imperfections inadequate for the part can be addressed by sanding, sandblasting, or orbital sanding.
The cold working process of shot peening is often used on die cast aluminum to improve fatigue resistance. Alternatively, a protective or decorative coating can be applied to the finished part, such as a powder coat. Other types of modifications can also be applied to the parts after casting, such as drill tapping.

Punching Technology

Metal punching process: how it works and solutions
What metal punching is and how does the process take place? Discover more about Suno’s metal punching process and the metals we can work with.
Suno is a metal punching company that performs work on both large and small quantities, from consulting and design to punching operations. Thanks to our established expertise, we are able to meet the customer’s needs to obtain finished and semi-finished products.

What is metal punching?
Metal punching is the process of impressing a form on a surface by pressure or percussion with a steel punch tool. In the metal punching process, the material is removed from a piece of sheet metal by applying a great enough cutting force. The metals that can be punched are different: steel, iron, copper, and aluminum. Everyone has their own hardness and needs adequate pressure to perform punching without imperfections.
How does the metal punching process take place?
The process starts with cutting and piercing sheet metal up to 25-30 mm thick to create precision metal parts. The pressure exerted by the punch on the sheet metal initially results in plastic deformation of the material and then, when the applied stress exceeds the shear strength of the material, there is a severing of the fibrous structure (which is typical of sheet metal) of the material resulting in the physical separation of the part within the tool.
What are the main steps of the process?
The cold metal stamping operation is carried out using dies mounted on presses. Specifically, it is carried out with a punch that, connected through a plate to the press slide, penetrates the die, cutting the sheet metal according to the shape of both the punch and the die (the contours of the punch and the hole in the die constitute the cutting parts that will operate the blanking).
The punched object falls under the die (and is picked up from there), due to the fact that the die has a section that widens from top to bottom.
As it descends, the punch penetrates the sheet causing its fibrous structure to deform, and the sheet begins to penetrate the die. In this way, the sheet metal deforms, with rounding of the punched edges, in the upper contact areas with the punch and lower contact areas with the die.
When the shear failure tension of the material is reached, a fracture surface is generated that separates the punched object from the rest of the sheet metal. Then the punch continues to push the punched piece inside the die until it falls out.
To ensure the correct positioning of the sheet metal above the die, there is a sheet metal guide system, and in the case of thin sheets, a sheet metal presser is also used to prevent the sheet metal itself, due to the stress caused by the punch, from bending and deforming during stamping, causing the production of deformed parts.
Metal punching machines
For the metal punching process, Suno uses TruMatic model automatic machines (punch press). The advantages of punching and laser cutting machining are combined in the TruMatic 7000 in a particularly profitable way. This high-end combination machine meets the most demanding requirements in terms of part quality, productivity, and flexibility. With the active die, scratch-free parts are obtained and maximum flexibility in forming is exploited.
Our metal punching units enable us to manufacture small and large sheets, for small or large production needs. With numerical control (CNC) punch machines can cut and form complex metal parts in an easy, quick and safe way. The punching process is numerically controlled 24 hours non-stop and entirely managed by our technical department.
Which metals can be processed?
Suno can operate sheet metal punching on different metals, each with its own specifics: steel, iron, aluminum, and copper. Due to the fact that the fibers of the metal at the recision do not cut, but undergo bending, and by virtue of the elasticity of the material and the bending stresses that accompany the shear stress imparted by the punch, punching does not result in a precise cut of the edges of the workpiece or hole, but in a more or less pronounced burring depending on when the tool is sharpened and the type of metal and its crystal structure.
Steel and stainless steel metal punching
Suno can apply a metal punching process on steel and stainless steel. Due to the hardness of these materials, punching should be done by placing sufficient force throughout the process, without reaching the breaking point.
Iron metal punching process
Iron is also a hard metal, which needs enough strength to be punched, limiting the smearing.
Aluminum metal punching
Unlike iron and steel, aluminum is a more ductile metal. This means that the metal punching process must be carefully programmed and checked.
Copper metal punching
Copper punching must take into consideration the breaking tension of the material, beyond which separation of the parts is caused. Also crucial is the use of special blocks to prevent unwanted deformation on the copper being worked, preventing the formation of sharp edges or irregularities.

Supplier Management Service

Supplier management is a critical component of any business operation that involves procuring goods and services from external sources. Effective supplier management involves developing and maintaining positive supplier relationships, managing supplier performance, and maintaining control over the supply chain. The first step in supplier management is to identify potential suppliers, evaluate their capabilities, and select those that match the requirements of the business. This process involves carrying out due diligence on each supplier to ensure that they have the necessary production capacity, quality control procedures, and compliance with industry standards. Once suppliers have been selected and contracts have been signed, ongoing supplier management involves monitoring supplier performance to ensure that products and services are delivered on time, within budget, and to the expected quality standards. This requires regular communication with suppliers, tracking and analyzing supplier performance metrics, and identifying and addressing any issues that arise. Supplier management also involves balancing commercial interests with the need to maintain good supplier relationships. This means negotiating contracts that are fair to both parties, managing supplier expectations, and avoiding any behavior that might damage the relationship with suppliers. By effectively managing suppliers, businesses can ensure that they have a reliable supply chain that can deliver high-quality goods and services that meet their needs and expectations. It also enables them to respond quickly to changes in market conditions and to capitalize on new opportunities as they arise.
