How does the stamping manufacturer customize the stamping, and the detailed process of the customized stamping process is as follows:
A general term for a stamping process that separates materials. It includes: blanking, punching, punching, grooving, sectioning, chisel cutting, edge trimming, tongue cutting, cutting, etc.
2. Lower shape
It is mainly a stamping process that cuts off a circle of excess material around the material to meet the size requirements
3. Cut the tongue
A certain part of the material is cut into a hole, but not all of it is cut. It is common that only three sides of the rectangle are cut and one side is left untouched. The main function is to set the step distance.
This process is uncommon, mostly for tubular parts that need to expand the end or somewhere outward into a trumpet shape
Just the opposite of flaring, it is a stamping process in which a tubular part needs to be narrowed inward at the end or somewhere
In order to obtain the hollow part of the part, the corresponding hole size is obtained by separating the material through the punch and the knife edge in the middle of the complete material.
7. Fine blanking
When the stamping part needs the section quality to be full bright band, it can be called “fine blanking” (Note: ordinary punching section is divided into four parts: slump band, bright band, fracture band, and burr area)
8. Full bright blanking
Unlike fine blanking, full bright blanking must obtain a full bright band in one step of blanking, while fine blanking is not
9. Deep hole punching
When the hole diameter in the product is smaller than the material thickness, it can be understood as deep hole punching, and the punching difficulty is that the punch is easy to break
10. Convex hull
Punch a protrusion on the flat material to meet the corresponding use requirements
Many friends understand forming as bending, which is not rigorous. Because bending is a type of forming, forming refers to the general term for all fluid material processes
A conventional process in which the corresponding angle and shape are obtained by plastically deforming the flat material through the convex and concave die inserts
13. Compression bars
This is generally used in sharp-angle bending forming inserts. It is mainly a structure that reduces the rebound of the material and ensures the stability of the angle by punching the material at the bending position.
A process in which a special pattern is pressed on the surface of the material through a punch. Commonly include: embossing, pitting, etc.
One of the molding processes is a process in which the shape of the product is curled into a circle
16. Flip hole
The process of inverting the inner hole of the stamping part to obtain a side of a certain height
It is mainly aimed at the situation where the product flatness is required to be high. When the flatness of the stamping parts is out of tolerance due to the stress, the leveling process needs to be used for leveling.
18. Plastic surgery
After the product is formed, if the angle and shape are not the theoretical size, it is necessary to consider adding a process for fine-tuning to ensure the stability of the angle. This process is called “shaping”
19. Deep drawing
It usually refers to the process of obtaining hollow parts from flat materials by means of a drawing process, which is mainly completed by convex and concave dies.
20. Continuous deep drawing
Usually refers to a stretching process formed by stretching the material in the same position multiple times through one or several dies in a material belt
21. Thinning and deep drawing
Continuous drawing and deep drawing belong to the thinning drawing series, which means that the wall thickness of the drawn part will be less than the thickness of the material itself.
The principle is similar to that of the convex hull, which is to make the material convex. However, drawing usually refers to automobile parts, which belong to a relatively complex forming series, and its drawing structure is also relatively complex.
23. Engineering model
In a set of molds, one stamping process can only complete one stamping process.
24. Composite mold
The general term for the molds that can complete two or more different stamping processes in one stamping process in a set of molds
25. Progressive die
A set of molds is fed by a material belt, arranging two or more processes in sequence, and feeding in sequence with the stamping process to finally reach a general term for mold types of qualified products
We have extensive experience in the design and manufacture of small but precise precision metal stampings. We always maintain close communication with customers, and help customers optimize the structure of parts from our perspective, so that the performance of stamping parts is excellent and the manufacturability is very good. The following editor of Yiwei Precision will introduce the process of customizing precision stamping parts.
1. We attach great importance to the preliminary development work. For the introduction of each new product, we will set up a project team to carry out special follow-up. For the development and manufacture of metal stamping parts, we gather the company’s experienced engineers in mold design and manufacture, process engineering, etc. to produce a detailed and rigorous DFM report on the product.
2. In mold design, we have also accumulated rich experience in design and manufacture. We use Winlead’s 3D design software to develop and design the mold. We have a strong knowledge database, bringing together many cutting-edge mold structures, and have the basic strength to develop various complex precision stamping parts. The mold material we use is ASSAB mold steel, and the mold parts we use are the well-known Misimi standard parts, Master hot runner and Sanwanji hot runner in the industry. We use Swiss Charmilles WEDM, Makino EDM and other equipment to process mold parts, and use German Zeiss CMM, high-precision Rockwell hardness tester and other equipment to conduct quality inspection of mold parts to ensure that mold accuracy meets manufacturing requirements.
3. After the customer confirms that the sample is qualified, we will carry out mass production. We use imported high-speed punching machines for stamping production, and the punching times can reach 800-1200/min. The production efficiency has been greatly improved, which can fully meet the needs of customers for urgent production.
Balford has passed ISO9001 in 2017. We have over ten years experience on manufacturing motor housing, solenoid valve housing and sensor housing, focused on auto parts.Now Balford enter into solenoid valve housings and sensor housings industry that are mainly based on difficult deep drawing process .
We employ documented procedures for every step in the manufacturing process from initial program launch through steady-state production in order to ensure consistent performance. We engineer our processes to produce the desired results, monitor those results, and use what we learn to regularly refine our processes as part of our commitment to continuous process and efficiency improvement.
Many of our customers have been with us for 5-8 years or more. Year after year, they experience zero late deliveries and zero returns.
