Professional Software Simulation: Interference checks are performed using a SolidWorks plugin before cutting, preventing 100% of the collision risk, avoiding part damage and die wear. The software enables users to simulate the bending process which enables them to forecast springback effects while adjusting bending parameters.
Advantages of Precise Calibration of Neutral Layer Factor (K-factor)
Accurate bending of complex custom parts requires precise measurement of the neutral layer factor (K-factor) because this measurement enables accurate bending results. Different materials and thicknesses have different K-factors, inaccurate calibration will lead to dimensional deviations.
Our organization has developed a complete material database which we used to determine the K-factor of various materials which meets accuracy standards. Internal testing shows that after precise calibration, the bending dimensional deviation is ≤±0.05mm, better than the industry average level.

LS Manufacturing Customer Case: Solving The Bending And Deformation Problem Of 5G Base Station Bracket For a Certain Aviation Communication Enterprise
The complex custom bending parts are easy to be deformed. After a lot of research work, we find that the deformation problem of thick and high strength parts is difficult to be solved with stamping.
But our high precision bending service can be achieved through the technology optimization. The case below show the solving of the deformation problem of 5G base station brackets for the aviation and communications corporation.
Customer Challenges
The 5G base station bracket for the company was made from 4mm thick 6061-T6 Aluminum alloy, with flatness which tolerates to 0.5mm and an annual demand rate of 2,000.
The initial stamping solution encountered 2 significant issues:
An excessive flatness of 30% parts remained after heat treatment, resulting in poor defect rate.
The week long delivery cycle of up to 45 days of progressive die led to project stagnation.
The customer contacted multiple service providers without success and ultimately chose us, hoping to solve the problem using the precision metal bending process.
LS 製造ソリューション
The analysis discovered that the fundamental reasons for deformation occurred because stamping construction had insufficient rigidity and stress release happened without control. The company switched to a high precision bending service after testing stamping which produced the following results.
<オル>
Laser Online Angle Compensation Technology: The CNC system uses a high-precision laser angle meter that provides real-time monitoring to correct springback deformation which causes bending deformation.
Stepped Stress Relief Process: Bending starts after stepped annealing has released internal stress while low-temperature aging maintains stable dimensions which prevent excessive flatness.
Optimized Bending Sequence and Parameters: SolidWorks plug-in simulation optimization reduced the number of processes from 6 to 4 and precise K-factor calibration ensured accuracy.
結果と値
The client received substantial advantages after solution implementation which resulted in the following benefits.
<オル>
The flatness deviation rate decreased from 30% to below 0.2% which reduced rework costs by $5,000 per month and the production pass rate reached 99.8%.
The company achieved significant cost savings through mold repair expenses which amounted to $3,000 with monthly costs for repairs and unit cost decreased by 22% which resulted in yearly savings of about $10,560.
The delivery cycle experienced a reduction from 45 days down to 12 days which allowed the company to handle urgent delivery requests while preventing project losses.
The client established a long-term partnership which resulted in them giving all future custom parts orders to us because they were highly satisfied with our services leading to annual business worth over $500,000.

What Are The Three Major Technical Standards That Procurement Engineers Must Verify When Selecting a Metal Bending Service Supplier?
The metal bending service requires evaluation of three factors which include automated programming capacity and real-time compensation system and dedicated material process database. The three criteria establish the degree of bending precision which impacts operational efficiency and total expenses.
Detailed Explanation of the Three Core Technical Standards
The following standards enable purchasing engineers to assess supplier performance because they help engineers verify vendor compliance with their purchase requirements.
Automated Programming Capabilities: The supplier must possess automated programming software and professional engineers capable of importing drawings to automatically generate and optimize programs, shortening processing time. This is critical in bending service supplier selection. Our system can reduce programming time by 60% with 100% accuracy.
Real-time Compensation System: The bending machine must be equipped with a high-precision linear scale and hydraulic compensation system to compensate for internal stress fluctuations in real time. Our equipment can stabilize tolerances within ±0.15mm.
Specific Material Process Database: The supplier must possess process data for materials such as titanium alloys and aerospace-grade aluminum, enabling rapid matching of optimal parameters. With over 20 years of experience and a comprehensive database, we can handle various complex materials.
Supplier Screening Checklist
The following checklist can be used directly to verify supplier qualifications:
<オル>
Do you have SPC data to prove mass production stability? Can you provide accuracy reports for the past 3 months?
Is your mold library comprehensive? Can you support small radius bending (R≤0.5T)?
Do you provide DFM reports to proactively optimize part structures and reduce metal bending costs?
Can you provide processing cases for similar complex, high-precision parts?
Can you provide DFM assessment and quotation within 24 hours?
よくある質問
Q1: How is that your bending accuracy can be 0.1mm, while normal factory is only 0.5mm?
LS Manufacturing uses CNC bending machines equipped with high-precision grating rulers and hydraulic compensation systems, which can real-time offset the angle error caused by internal stress fluctuations in materials, and accurately calibrate the neutral layer coefficient to ensure accuracy far beyond ordinary factories.
Q2: 50 bending features in my part, is it better to blank it or to bend?
For many features with high density, Stamping has a big benefit on one-time forming. If the annual order quantity is less than 1000 sets, the amortized mold cost of stamping will make the unit price not acceptable.You should contact LS Manufacturing to do process breakdown and optimize to get the best cost.
Q3: Aluminum alloy 6061 can be broken in bend. How do the LS Manufacturing do?
Because we take strict control of the minimum bending radius ( R 1.5T) and the elasticity, employing para-gravimetric bending and the local annealing, it results in 90-degree accurate forming without influences on the mechanical properties of the aluminum. The bending breakage is end up.
Q4: Will mold creases formed upon bending be visible on the anodised surface?
Not at all.We use a type of film and mold that do not have scratches on the surface of exterior parts and totally meet the surface inspection standards of high-end consumer electronic products and medical products, does not affect next dyeing and other surface treatments.
Q5: What is the highest bending thickness you are capable of?
We have a 500 ton bending center, which can consistently for custom parts with carbon steel at 20 mm thick and stainless steel at 12mm thick, keep perpendicularity tolerance for the thick part and satisfy the heavy-duty parts process.
Q6: Why does the price of a bent parts varied form batch to batch?
Raw material cost changes and batch order quantity mainly affect this. For example, LS Manufacturing has the sliding fee.The more batch order quantity is, the lower cost per die change will be, so the metal bending cost is more cost efficient. And it offsets unit price change effectively.
Q7: DBM do free DFM(Design for Manufacturing) assessment for bend parts?
はい。 After you submit the drawings, our senior engineers will do analysis for you and offer some optimization recommendations to drive down manufacturing difficulty and cost like combine two or more bending surfaces, optimize cut way, etc. free of charge.
Q8: Will you send me inspection report (SGS / TUV) for third-party after the order is finished?
Of course, we put the strict ISO quality management system in place. All shipped parts will pack with material certificate and CMM dimension inspection report from Zeiss. If you also want the third-party test reports, please tell us in advance. We will do our best to assist.
