Digital Manufacturing FAQs

We’re eager to get to know you, your business, and how we can help. From Metal spinning services to traditional manufacturing, prototypes to large-scale production runs, we’re ready to get to work.

1.What is the advantage of working with BE-CU? Why should I choose your company to make my parts?

Our industrial CNC metal spinning, CNC machining, die making and stamping services provide parts made directly from the customer’s 3D CAD model, reducing the likelihood of errors.

2.What companies do you work with?

Due to the proprietary and competitive nature of projects we work on, we do not disclose a listing of our customers. However, we do regularly receive permission to share customer success stories. Read our success stories here.

3.Is a Non-Disclosure Agreement (NDA) required to do business with BE-CU Spun Company?

An NDA is not necessary to do business with BE-CU Spun Company. When uploading your CAD model to our site, we employ state-of-the-art encryption and anything you upload is protected by confidentiality obligations. For more information, contact your account representative.

4.What industries use BE-CU Metal Spinning services?

We serve a variety of industries including medical device, automotive, lighting, aerospace, technology, consumer product, and electronics.

5.When should I use metal spinning versus stamping?

Before making the investment to have stamping tooling made or high-volume machining processes, you likely will want to test a part that is as close to the production part as possible. Metal spinning(1-10k) is the best option for this situation.

Additionally, engineers often need just one or maybe a few parts for test fixtures, assembly jigs, or assembly fixtures. Machining(CNC Turning) is the best option here as well, but traditional machine shops often charge a significant non-recurring engineering (NRE) charge for programming and fixturing. This NRE charge often makes getting very small quantities not affordable. The automated CNC machining process eliminates the upfront NRE costs and is able to offer quantities as low as one part at an affordable price and get parts in your hands in as fast as 1 day.

Metal stamping is better suited to support larger amounts of samples for functional or market testing, bridge tooling, or low-volume production. If you need parts before a steel tool can be made (typically 6 to 10 weeks with other molders) or your volume requirements don’t justify expensive steel production tooling, we can supply production parts to meet your full requirements (up to 100,000+ parts) in 1-20 days.

6.How many machines do you have?

We currently have more than 40 cnc spinning machines,punch, high speed stamping machine, presses, press brakes, and other manufacturing equipment. With our long history of growth, this number is always changing.

7.Are my parts made in the China?

We currently have 2 manufacturing facilities in the Zhongshan and Jangmen, all of which are producing spun metal parts.

8.How do I get a quote?

To get a quote for all of our services, simply upload a 3D CAD model on our site. You’ll get an interactive quote within hours with free design feedback. If there are problem areas in the submitted design, our quoting engine provides detailed information on the potential manufacturing issues and suggests possible solutions.

9.Can I quote my part with all services at once?

You can get a quote for spinning and deep drawing stamping.

10.What types of files do you accept?

We can accept native SolidWorks (.sldprt) or ProE (.prt) files as well as solid 3D CAD models from other CAD systems output in IGES (.igs), STEP (.stp), ACIS (.sat) or Parasolid (.x_t or .x_b) format. We can also accept .stl files. Two-dimensional (2D) drawings(As PDF)are accepted.

11.I don’t have a 3D CAD model. Can you create one for me?

We do not offer any design services at this time. If you need assistance creating a 3D CAD model of your idea, contact us via email and we’ll get you contact information for designers who are familiar with our process.

12.Does BE-CU offer finishing options and secondary processes with its services?

19.How can I pay?

We accept payment via bank transfer to Hong Kong or China. Payment is also accepted via Paypal though there is a 4% service charge for this. Paypal can accept certain credit card transactions.

20.What about credit and payment terms?

We generally request customers work to our standard payment terms for at least the first order. These are 50% deposit and 50% prior to shipping. It is possible to negotiate other payment terms such as Net 30, but these are agreed on a case by case basis.

1.Is metal spinning practical or feasible for me?

A. We always need some kind of drawing (a hand sketch will do). A discussion over the phone usually is enough to see if the job is feasible. A print is needed for a firm price along with a delivery date.

2.What is metal spinning?

A. Metal spinning is a "cold worked" metal forming process in which sheet metal is formed over a rotating mandrel or form. It is an "age old art" that has been practiced manually for centuries (see History of Metal Spinning).

3.What shapes can metal spinning produce?

A. The most common shapes are hollow dished, conical, hemispherical, and elliptical shapes. Edge configuration that includes beads and hems are also accomplished with metal spinning. Due to the nature of the process, most spinnings are round. In some instances spinning can be combined with other forming processes to produce slightly irregular shapes.

4.What are typical tolerances that can be achieved with metal spinning?

A. Typical tolerances for manual metal spinning are +/- 1/15" although with proper gauges tighter tolerances can be achieved on some dimensions.

5.What materials can be spun?

A. Spun parts can be made from many metals. The most common metals are steel, aluminum, stainless steel, brass, and copper. Silver and other exotic alloys can also be used.

6.What is the smallest and largest part you can make?

A. The chart below outlines our capabilities with regard to common materials and our minimum-maximum capacity. Keep in mind that material thickness is an important factor as well.

Metal Diameter Of Parts
Aluminum Spinning .150-46”
Copper Spinning .125-46”
Brass Spinning .125-46”
Mild Steel Spinning .150-46”
Stainless Steel Spinning .125-46”

7.What if a design change requires a change in diameter?

A. If the changes causes the inside diameter to decrease in size, the change will be relatively inexpensive. If the inside diameter increases, new tooling will have to be produced. If you need a prototype, this is the cheapest way to go; changes are the least expensive by the spinning process.

1.What are progressive die metal stampings?

Progressive die metal stampings are custom metal stampings produced with a progressive die stamping machine. There are three types of common metal stampings: progressive die, multi slide and deep drawn. Of these three types, progressive die are the most common. These machines often run faster and with more accuracy due to pilots in the dies.

2.What advantages are there to deep drawn metal stampings?

Deep drawn metal stampings have several advantages. These parts stamped from a flat strip of material (stainless steel, copper, aluminum, etc.) and through a series of die sets drawn or stretched into a cup or tube shaped part. One advantage is the ability for the final part to be seamless. Other advantages of deep draw metal stamping include nearly limitless O.D. to I.D. combinations, different shapes other than round stampings, and better control of part dimensions.

3.What differentiates you from other metal stamping companies?

The biggest difference between BE-CU Spinning., Inc. and other metal stamping companies is our ability to produce three types of metal stampings (progressive die stampings, deep draw metal stampings and multi slide metal stampings). We also have a very diverse customer base (medical stampings, battery stampings, etc.). Most other metal stamping companies only serve a few industries and are more exposed to the fluctuations in these industries. BE-CU follows ISO 9000 and AS 9100 (aerospace) quality systems in all our operations.

4.What’s the difference between your precision metals stampings and fineblanking?

Fine blanking machines move from two directions. Both the punch and the die move toward each other simultaneously. Unlike a precision metal stamping machine which moves only the punch or die set while the other remains stationary. Fine blanking results in a part with no burr. The shear and break in custom metal stamping machines will always result in some burr on the part. BE-CU has the finishing facilities for cleaning and deburring any parts we manufacture, or your existing metal components.

5.Will you drop ship your stampings directly to my customer?

BE-CU daily ships our custom metal stampings around the world. We can drop ship, ship to a plater then on to you, or any other location. We can ship your precision metal stamping in infinite ways; boxes, returnables, tubs and by land, sea, or air.

6.When die stamping metal components, how do you choose the right process?

To choose between multi slide stamping, progressive die stamping or deep drawn stamping, our engineers concentrate on the complexity and shape of the desired finish part. For example progressive die stampings can have more piercings and multiple forms, flatter parts at faster speeds than deep draw or eyelet machines. Whereas, deep draw or eyelet stamping machines lend themselves better to production of stampings deeper or taller than ½ inch. Multi-slide or four slide machines work best for the production of multiple formed parts, wire forms or parts requiring the most accuracy.

7.Does BE-CU Spinning., Inc. stock finished metal stampings?

Most of the time the answer to this will be no, BE-CU produces metal stampings to customer specifications. However, there are times we will have stock of the exact alloy you need. However, even if we do not have stock, we can often have the tool completed for your custom stampings in ten weeks or less.

8.Does BE-CU Spinning., Inc. have any distributors?

BE-CU Spinning., Inc. does not work with any distributors. All of our custom drawn wire and metal stampings ships from our factory in Zhongshan,China.
