How Do Multi Directional Standard Folding Setups Support Low Cost Custom Bending Runs?
Using multi-directional folding fixtures, it is possible to carry out bi-directional bending in one go without human intervention and so, lower the cost of small-batch, multi-variety customization. This is one of the critical process configurations for low cost custom bending.
Efficiency Bottlenecks of Unidirectional Bending
Typical unidirectional bending machinery has great difficulty in processing folded parts with two bends facing different directions. It is unable to cope with flexible production demands during the manufacture of complicated custom bending components, which gives rise to multiple issues with both efficiency and costs:
<オル>
Manual Flipping: After each bend, the operators must stop the machine to flip the sheet manually by 180°.
Positioning Error: The cumulative positioning errors increase due to multiple flips.
High Changeover Costs: This leads directly to very high labor costs for multi-variety, small-batch productions.
Flexibility Advantages of Bidirectional Folding
There are CNC bending machines and a modular tooling system in the shop that will meet the small-batch, low cost custom bending requirements after which flexible bending manufacturing capabilities will be strengthened. The main advantages of the process are:
<オル>
Automatic Bidirectional Bending: With the core pressure plate, the sheet is firmly held, and two sets of folding blades perform high speed bending in opposite directions automatically.
One-Time Completion: The sheet has to be set by the operator only once at the feed end, and the machine will carry generally process by itself.
Low switching costs: Small batch switching costs for parts could be nearly zero.
LS Manufacturing Helps Global Communication Giants Optimize High Precision 5G Base Station Aluminum Alloy Heat Dissipation Case for Customized Bending Processing
Customer Challenge
A major European telecom giant encountered difficulties technically and economically in improving the 6063-T6 aluminum alloy heat dissipation casing for their 5G base station. The item was composed of eight composite bend parts while the original drawings had complicated radius angles, which led to frequent mold changes and single-piece debugging time up to 8.5 minutes.
6063-T6 aluminum alloy is not suitable for deep drawing and very small radius angles may cause stress cracking which on its turn yields 72% of product qualification rate only. Surface scratches caused by steel mold bending brought about high monthly costs for polishing and the customer ultimately had low return on investment, besides that the mass production was severely affected.
LS Manufacturing Solution
Drawing upon our 5G base station project experience, we believe even small design changes at the design stage would be able to yield significant cost advantages. After we started to work on the project, the engineering expert team at LS Manufacturing expeditiously performed complete DFM (Design for Manufacturing) engagement and process reengineering:
<オル>
Standardized Radius: We managed to convince the customer to make the radius of all bends uniform to 1.5mm (roughly 1.2 times the plate thickness). That ensured that grain flow during bending was good, that there was no risk of bending cracks(100% of risk was removed), and the parts could be completely finished in a single setup on a multi-axis bending machine without tool changes.
No-Cut Process: For this the customer requested not only area indentations but also a very high level of precision so that a 0.2mm thick polyurethane anti-indentation film serves as the physical insulation layer.
Process Enhancement: With the help of offline 3D software, the process steps have been updated to use a 6-axis back gauge CNC folding in an automated, bidirectional manner to completely eliminate bending edge/back gauge interference.
結果と値
After the full deployment of DFM optimization solution, product processing efficiency and quality were greatly enhanced: the bending time per piece was cut down from 8.5 minutes to 2.3 minutes, which is an efficiency gain of 72.9%, bending accuracy always met standards, and the pass rate went up from 72% to 99.8%, with indentation and grinding costs completely eliminated.
This optimization enabled the customer to reduce the price per piece by 31.5%, halve the delivery cycle time, and save over $120,000 annually in procurement costs, thereby fully illustrating the commercial value of DFM bending optimization.

よくある質問
Q1: What is your maximum metal bending thickness limit?
We have a 250-ton CNC bending machine, which allows us to bend low-carbon steel up to 12mm in thickness and stainless steel up to 8mm in thickness. Through stringent accurate bending process control, we can keep the finished product tolerance within 0.15mm, at the same time flexibly meeting various thick plate bending requirements.
Q2: How do you prevent springback in high-strength metal bending services?
We obtain the main mechanical strength parameters of every batch of metal materials beforehand and couple it with a top-notch Wila CNC hydraulic bottom dead point dynamic deflection compensation system. This is capable of correcting bending springback errors to 0.01mm at the precision level, thereby guaranteeing stable bending accuracy of high-strength metals.
Q3: Can you provide a fast metal bending quote for custom prototypes?
Yes, we offer quick quotation services for custom prototypes. You may upload your drawings directly. Our technical experts promptly conduct a DFM evaluation within 24 hours after receiving your 3D drawings in STEP or DXF formats. This way, you are able to get a quote fast and generate your formal and accurate bending quotation.
Q4: How do you ensure surface quality for custom bending components?
We adopt a continuous processing technology that uses precision nylon bending dies at every stage of our production line. Besides, to prevent friction and pressure between the die and the sheet metal, we cover the die with a highly wear-resistant special polyurethane seamless protective film. As a result, custom bent parts reach 100% are scratch-free and indentation-free surfaces.
Q5: What is your minimum order quantity for low-cost custom bending?
We are very flexible with custom needs. We can give you different product types and small batches. Strictly speaking, we don't fix a minimum order quantity. Even a single sample order can utilize our advanced CNC offline programming technology and standardized low-cost bending processing services.
Q6: How do you avoid crack risk in 6061 aluminum custom component bending service?
About 6061 aluminum alloy bending, a bending radius of 1.5-2.0 times the sheet thickness is required. And the bending line is made perpendicular to the sheet rolling direction, so the aluminum bending at the source is completely free from the risk of cracking.
Q7: What international standards does your bending service supplier comply with?
Our factory will be continuously doing the whole process with the ISO 9001 quality management system and the IATF 16949 automotive industry standard very strictly.

Q8: How do you manage intellectual property for proprietary cost-effective metal bending?
We are able to sign NDA confidentiality agreements compliant with regulations and set up a multi-layered firewall digital drawing access control system to strictly handle client-customized drawings and core process data, because of this fully ensuring the absolute security of client intellectual property rights.
概要
Custom metal bending's main source of profitability is not reducing the cost of raw materials per unit, but rather making the most out of the details like the reuse of standard radius angles, the automatic compensation of springback, continuous flows, and the optimization of processes (DFM) to both uncover and eliminate hidden processing losses while increasing the usefulness of the procurement budget. Anyway, bad bending layouts and processes that are not thought out properly will constantly eat into project profits.
