Custom Automated Assembly Machine Manufacturer

To triple their electrical steering unit production, the German automotive supplier did not buy more robots. Instead, they searched for a custom automation solution for their full assembly required from the first stamped metal part to the last tested, serialized unit. They spent 18 months developing from a concept to commissioning, ultimately producing one steering unit every 12 seconds with less than 10 operators on the shop floor. Although it was a lot of money for investment, the return was great. For any manufacturer who faces similar challenges such as: (a new product, (labour shortages), (quality problems with manual assembly), a custom automation builder should be worked with strategically. Identifying the appropriate partner for your needs will be through the hundreds of integrators/machine builders worldwide is the first and possibly most significant step in your endeavor.

What Is a Custom Automated Assembly Machine?

A custom automated assembly machine is a special type of production machine that carries out a series of processes (e.g. feed, position, join, secure, weld, inspect, label and package) without any physical human involvement. Unlike standard robotic workcells which can be re-used for multiple products, a custom assembly machine is designed specifically for a single product or product family. This is analogous to a custom suit; each station, fixture and sensor within the machine has been included specifically because it is required for the product being manufactured. Custom assembly machines are built by specialist engineering firms that provide solutions integrating mechanical engineering, control systems, pneumatic systems, robotic equipment, optical systems and software into one functioning validated solution. Therefore the final product delivered is not a “catalog” item but rather a turnkey manufacturing solution that will produce; meet a specified time (Takt), meet a specified quality and/or cost criteria. For an in‑depth look at the technologies that underlie these systems, our guide on what automation is provides a foundational overview.

Notable Custom Automated Assembly Machine Manufacturers

The global landscape includes a mix of large multinational automation integrators and focused, independent machine builders. The table below summarises several recognised names, along with a representative mid‑range builder.

Why Manufacturers Invest in Custom Assembly Automation

The commissioning decision for a custom assembly line is rarely focused on replacing one operator. Rather, it is usually driven by a need to solve a variety of combined issues, many of which cannot be resolved with an existing ‘off-the-shelf’ piece of equipment. The most common reasons for commissioning new equipment are as follows:

• Product complexity that defeats manual assembly. Because a medical device has many small parts that must be positioned, oriented and joined together in a clean room, this device is an ideal candidate for automating assembly processes.
• Quality requirements that exceed human consistency. Missing an O-ring or a negligent torque on a bolt can lead to life-threatening situations in and around automotive safety equipment. An automated product inspection process can apply the same amount of force every time, verify each operation of the assembly, and reject any defectively constructed assemblies.
• Labour availability and cost. Automation can allow a manufacturing bottleneck to become an advantage–in situations where there are high prices and/or a shortage of skilled assembly labour.
• Throughput demands. To fulfil a new contract, an average of 100 units each shift will need to increase to 500 units per shift. A completely designed automated production line capable of producing the exact number of units needed will achieve this.

Key Criteria for Evaluating a Custom Assembly Machine Builder

The ability to create an operating customised automated assembly machine is not available at all machine shops. There is a significant disparity between what general fabricators can do vs true automation integrators. As a result, the choice of automation integration partner may result in a machine with either failure to reach their specified rate of production, failure to meet quality specification or an automated machine that simply doesn’t operate as intended. The following criteria are used to help establish a successful vendor selection versus an inappropriate selection:

• Domain experience. Has the builder delivered machines for your business? The automotive, medical device, electronics and consumer goods industries have different regulations, cleanliness and validation requirements. A builder who has done it before learns how to deliver from experience, thus there would be an established learning curve (on your budget).
• In‑house engineering depth. Core Competency for the Company Should Be Mechanical Design, Electrical Design, PLC Programming, Vision Integration and Robotics. Outsourcing Controls Engineering Will Put The Builder At A Disadvantage When Attempting To Troubleshoot A Complex Sequence; They Will Also Blame Others For Any Problems That Occur During The Debugging Process.
• Project management rigour. Each custom line is an independent project which has a defined scope, cost, and schedule. The customer will gain assurance that the manufacture can build the equipment according to specifications through a linear process that includes a comprehensive project management plan, a formal design review process, a factory acceptance test (FAT) at the manufactures facility, and a site acceptance test (SAT) at the end-users facility. If the project contract does not define these milestones for the manufacture any delay in the project will be the fault of the manufacture, therefore putting more risk on the customer.
• After‑sales support and spares. An additional supply of replacement sensors, actuators, and wear parts will be necessary for a machine that operates 24 hours a day and 7 days a week. With a builder who maintains an inventory of essential spare parts near the machine or can deliver those parts within twenty-four (24) hours, it is possible to prevent the complete shutdown of your manufacturing line when just one (1) part fails.

What Determines the Cost of a Custom Assembly Machine?

Cost for a custom automated assembly machine can vary tremendously which makes it impossible to provide an actual number. For example, a simple benchtop pick-and-place cell typically costs around $50,000 while a fully automated, validated, medical device assembly line complete with vision inspection at each workstation, enclosed within a clean room, and comprehensive traceability software may run upwards of $5 million. The following list includes some of the key components that contribute to overall cost:

• Number of assembly stations and complexity of each operation. Each station adds mechanical structure, actuators, sensors, and controls.
• Required throughput (takt time). An assembly line that produces components every three seconds requires faster actuators, tighter control systems, and more robust designs compared to an assembly line producing components every thirty seconds.
• Vision and inspection requirements. Manual Lines cannot provide the verification capabilities that can be achieved with higher resolution of cameras, lighting and processing hardware.
• Regulatory compliance. Engineering documents and test costs accumulate as a result of all validation by the FDA, CE Mark, ATEX Certification and other mandated requirements by an organization.
• Material handling and feeding. Bowl feeders, tray feeders, and conveyor systems must be tailored to the specific components.

If efficiently managed, an investment will yield a good return on investment (ROI) after about 18 – 36 months due to labor savings, decreased scrap, improved throughput, and improved quality. The most important thing is to partner with a general contractor who can give a sound estimate of the costs associated with building based upon a clearly defined specification; this is much more helpful than working from a highly generalized idea of what the results will be.

How to Choose the Right Manufacturer for Your Project

Choosing a manufacturer of custom automated assembly machinery is a purchase that benefits from careful attention to detail when performing the procurement process. Employing a systematic approach:

1. Define your requirements precisely. What are the specifics of the product and any associated performance requirements? When should production start? How much will production cost? What types of quality control will be completed? What will the operational budget be? If an RFQ clearly specifies what is needed, there is a higher likelihood that the supplier will submit a serious proposal.
2. Visit the builder’s facility. More than what you would find in a brochure, a factory tour can show you the machines being assembled and allow you to talk directly to engineers instead of just to the sales team. Also, make sure that you see one of the machines working that is similar to yours.
3. Check references. Talk to past customers to see how the machine performed; what was the cycle time compared to the actual delivered date and whether or not the machine received any follow-up service is also important.
4. Clarify the acceptance criteria. The contract should outline the milestones of both the FAT and SAT. These would include the types of tests being performed, the criteria for passing those tests, and what actions will be taken in the event of a failure of a machine.
5. Evaluate the total cost of ownership. The initial purchase price is just one of the costs associated with owning a machine for 10-15 years. The other costs include spare parts, maintenance training, and the ongoing support of the manufacturer.

Pertanyaan yang Sering Diajukan

What is the difference between a standard assembly machine and a custom one?

Standard assembly machines are pre-engineered platforms that allow users the ability to adapt to multiple products, usually within limitations. An example of this is an indexing table that has interchangeable tooling features allowing users the flexibility to assemble products efficiently and accurately. Custom assembly machines are engineered with one specific application in mind. Every assembly mechanism (station) and assembly fixture (tool that is attached to a product) is designed with the specific product’s shape, material, and assembly method in mind.

How long does it take to build a custom automated assembly line?

Lead time differs from project to project based on their level of difficulty. A single station device may have a 4-6 month lead time from request until delivered, while a multi-station fully automated system with extensive testing/validation can range from 12-18 months (or greater) depending on the customer’s specific requirements? Timeline should include the following components: Design Review; Procurement; Build; Factory Acceptance Test; Shipping; Installation; and Site Acceptance Test.

Can a custom assembly machine be modified for a new product later?

To a certain extent, Yes. A properly constructed machine has some flexibility in the way that both fixtures and programs are set up. This machine, however, is custom made. Therefore, if you have a major change to the product — such as the dimensions of the product or new types of components — you will need to re-engineer the machine to accommodate those changes. You should consult with your builder about adding a measure of flexibility in the design stage because it will be less expensive to add these features during initial construction than to create them later as a retrofitting process.

What industries use custom automated assembly machines?

Custom automation dominates virtually all industries which manufacture mass-produced physical goods. Major examples include the manufacturing of automotive and electric drive componentry, medical devices and disposables, consumer electronics, electical protection devices (MCB’S & MCCB’S), pharmaceutical packaging and sub assemblies used in the aerospace manufacturing process. In other words almost any product that has a repetitive assembly sequence and/or requires a certain level of consistency in quality/durability could be automated.

Commissioning a custom automated assembly machine is a capital decision that reverberates through a manufacturing business for a decade or more. The right machine, built by the right partner, becomes a competitive moat: it lowers cost, raises quality, and enables a production rate that competitors cannot easily match. The wrong machine becomes an expensive piece of idle floor space. The difference lies in the rigour of the selection process — the clarity of the specification, the depth of the builder’s relevant experience, and the structure of the project milestones that govern the build. Benlong Automation is one of the companies that provides this rigour for the electrical manufacturing sector, translating decades of domain knowledge into assembly lines that produce tested, certified devices at the pace that global markets demand.
