Contract Manufacturing of Serial Metal Products

Why move serial metal products to contract manufacturing

For companies in Tashkent and the regions of Uzbekistan, it is now critical to bring products to market quickly and scale volumes. At the same time, the in-house shop is often already loaded: current products are being produced, existing customers are being serviced, and minor improvements are underway.

Contract manufacturing of serial metal products allows you to:

• launch a new product without stopping your current business;
• test the market and design without investing in new equipment;
• shorten the time from idea to first sales;
• turn a successful prototype into a stable series with predictable cost price.

The key to this is a properly structured “prototype — test — series” cycle and a clear calculation based on the technical specification (TS) at each stage.

What tasks the “prototype — test — series” cycle solves

The cycle is needed not only for engineers, but also for owners/managers:

• For the business — to understand whether the product will pay off without blocking the main order flow.
• For designers — to check how manufacturable the design is: how convenient it is to cut, bend, weld, paint.
• For procurement — to assess the availability of materials in Uzbekistan, substitution options, and impact on price.
• For sales and marketing — to get a real sample, test it with customers, and collect feedback.

Breaking the process into three stages allows you to gradually reduce risks: first you test the idea on a prototype, then the manufacturability and operation on a test batch, and only after that you move to a stable series.

What products make sense to outsource to contract manufacturing

Contract manufacturing is especially effective for serial and modular metal products:

• Small and medium-sized metal structures: frames, trusses, columns, stairs, railings, canopies, platforms.
• Structures for outdoor advertising and retail fit-out: frames for signs, lightboxes, 3D letters, brackets, stands.
• Food equipment and stainless steel products: tables, sinks, racks, frames for food-processing.
• Components for solar/PV: mounts for solar panels, mounting rails, support elements.
• Interior and furniture: metal frames for tables, stands, partitions, decorative structures.

The common feature is repeatability. The more repetitions of a part or assembly, the more profitable it is to move them to contract manufacturing.

Entry point: what should be in the TS for calculation

The calculation based on the TS is the starting point of the “prototype — test — series” cycle. The completeness of the initial data determines both the accuracy of the price and the lead times.

Minimum data set for an initial calculation:

1. Product purpose

   • where and how it will be used (outdoors/indoors, industrial environment, food contact, etc.);
   • required service life.

2. Dimensions and design

   • overall dimensions (length, width, height);
   • scheme or sketch (drawing, 3D model, at least a rough sketch with dimensions);
   • stiffness and load requirements (if any).

3. Material and finish

   • intended material: mild steel, galvanized steel, stainless steel;
   • metal thickness;
   • whether powder coating is needed, which colors;
   • requirements for welds and surface quality.

4. Volume and logistics

   • planned volume: prototype, test batch, series (pcs/month);
   • delivery format: on-site assembly, installation, pickup/delivery within Tashkent or to the regions.

5. Timing

   • desired date for receiving the prototype;
   • approximate timing for launching the series.

The more precise the TS, the easier it is to select optimal technologies (laser cutting, metal bending, welding, powder coating) and offer options in terms of price and lead time.

Stage 1. Prototype: fast launch without stopping your current business

Goal of the stage

To make the first working sample, as close as possible to the planned series, but without excessive costs for production setup.

What it looks like technologically

1. Clarifying the TS and refining the design

   • checking drawings for manufacturability with the available equipment;
   • if necessary — simplifying assemblies, changing thicknesses, selecting standard profiles.

2. Selecting technologies for the prototype

   • laser cutting for precise part geometry;
   • CNC metal bending for repeatable angles;
   • welding (MIG/MAG, TIG — depending on the material and weld requirements);
   • basic or final powder coating.

3. Manufacturing a single unit

   • without complex tooling, using universal tools;
   • with recording of all operations and actual time — this is the basis for series calculation.

What you get

• a physical sample for fitting, testing in real conditions, and demonstrating to customers;
• understanding of actual weight, stiffness, and installation convenience;
• an initial estimate of cost price and design bottlenecks.

At this stage, your core business continues to operate as usual: the new product is being “run in” externally.

Stage 2. Test: refining the design and production technology

Task of the stage

To turn a successful prototype into a test batch (usually from several to dozens of units) to check:

• quality stability in repetition;
• installation and operation convenience for the end customer;
• coating and joint behavior over time;
• logistics: packaging, transportation, storage.

What happens at the test stage

1. Design optimization

   • re-nesting parts to reduce waste in laser cutting;
   • changing joint and weld locations to speed up welding;
   • simplifying geometry for stable metal bending.

2. Process tuning

   • selecting cutting and bending modes for a specific material and thickness;
   • choosing the welding method and sequence of operations;
   • fine-tuning powder coating modes (layer thickness, surface preparation).

3. Fixing standards

   • time for each operation;
   • consumption of material and consumables;
   • quality control requirements.

Result

• you see how the product behaves “in series”;
• you can adjust the design before launching large volumes;
• a basis is formed for calculating a stable price for serial production.

Stage 3. Series: how to organize stable batch production

When the prototype and test batch have confirmed the viability of the solution, serial contract manufacturing begins.

How the series is organized

1. Planning volumes and schedule

   • agreeing on a monthly/quarterly production plan;
   • defining a buffer stock in the warehouse (if needed).

2. Production preparation

   • manufacturing or selecting the necessary tooling and jigs;
   • approving process sheets and operation standards;
   • training personnel for the specific product.

3. Batch production

   • cutting, bending, welding, powder coating according to the established process;
   • quality control according to approved criteria;
   • packaging and shipment according to the agreed schedule.

What this gives your business

• predictable lead times for serial products;
• stable quality from batch to batch;
• unloading of your own shop and team;
• the ability to scale volumes without additional investment in equipment.

Technologies: laser cutting, bending, welding, powder coating, machining

Contract manufacturing of serial metal products relies on a set of technologies.

Laser cutting

• high accuracy and repeatability of parts;
• minimal burrs and good preparation for welding;
• efficient sheet nesting to reduce waste.

Metal bending

• CNC bending ensures stable angles and dimensions;
• ability to implement complex shapes without additional welds;
• reduced assembly time and increased structural stiffness.

Welding

• joining elements of frames for hangars, trusses, columns, stairs, railings, canopies;
• selecting the welding method for the material (mild steel, galvanized steel, stainless steel);
• controlling deformation and geometry in serial production.

Powder coating

• corrosion protection for outdoor advertising, urban structures, solar/PV;
• decorative coating for furniture and interior solutions;
• consistent color and texture from batch to batch.

Additional operations

• threaded joints, drilling, cutting profiles;
• assembly of units and finished products;
• packaging for transportation within Tashkent and to the regions.

Materials: mild steel, galvanized steel, stainless steel, combined solutions

Material choice directly affects technology, price, and service life.

Mild steel

• optimal for indoor metal structures, furniture, interior solutions;
• requires protection (powder coating) for outdoor use;
• well suited for frames, stairs, railings, canopies.

Galvanized steel

• a logical choice for outdoor structures and aggressive environments;
• often used for fasteners and mounting rails for solar/PV;
• allows reducing coating thickness requirements.

Stainless steel

• essential for food equipment: tables, sinks, racks;
• in demand in pharma, cosmetics, food-processing;
• imposes higher requirements on welding and surface treatment.

Combined solutions

• load-bearing frame made of mild steel + stainless or painted elements in the product contact zone;
• combination of metal with wood, glass, composite for outdoor advertising and interiors.

At the TS calculation stage, it makes sense to consider several options for materials and finishes to find a balance between product life and budget.

What affects the price: key cost factors

Below is a generalized table of factors that most often affect the final cost of contract manufacturing of serial metal products.

Important: without a specific TS it is impossible to quote an exact price. In practice, it is always useful to consider 2–3 implementation options (material, thickness, coating, batch size) and compare them by budget and lead time.

Typical mistakes when launching serial contract manufacturing

1. Designing directly for series without a prototype

   As a result, some solutions turn out to be inconvenient or too expensive to produce, and changes at the series stage cost more.

2. Insufficiently detailed TS

   Missing dimensions, loads, and operating conditions lead to repeated approvals, schedule shifts, and price recalculations.

3. Ignoring material availability in the region

   A material that is difficult or slow to procure in Uzbekistan can disrupt series deadlines.

4. Overly strict or, conversely, vague quality requirements

   Excessive requirements increase cost without real benefit, while vague ones lead to a mismatch between expectations and result.

5. No volume plan

   When volumes “float”, it is difficult to optimize production, keep the price, and ensure stable lead times.

6. Late involvement of production in the project

   If the designer develops the product without considering real technologies (laser cutting, bending, welding, powder coating), unexpected constraints appear at the series launch stage.

7. Poorly thought-out logistics and installation

   Dimensions, weight, and assembly scheme do not take into account real conditions on site, which increases installation time and cost.

Timing: how to plan the cycle without stopping your business

Timing depends on product complexity, production load, and material availability, but the planning approach itself is fairly universal.

How to structure timing by stages

1. Prototype

   • agreeing on the TS and calculation based on the TS;
   • manufacturing and delivery of the first sample.

2. Test batch

   • taking prototype improvements into account;
   • producing a limited series;
   • collecting feedback from operation.

3. Series

   • production preparation (tooling, process sheets);
   • reaching the planned delivery rhythm.

How not to stop your current business

• allow time for approvals within your company;
• plan windows in advance for testing products on site;
• avoid overloading your own shop with small pilot batches — transfer them to contract manufacturing;
• use a pilot region or a limited pool of customers to run in the product.

With competent planning, the “prototype — test — series” cycle runs in parallel with your current activities and does not block your core revenue.

FAQ on contract manufacturing of serial metal products

1. Can we start without a full 3D model, using only sketches?
Yes, at the start a clear sketch with dimensions and a description of operating conditions is sufficient. As you work on the prototype, the design can be refined and converted into 3D.

2. Is it mandatory to use stainless steel right away for food equipment?
Not always. For some areas, combined solutions are possible: a load-bearing frame made of mild steel with coating, and contact surfaces made of stainless steel. This is discussed at the TS calculation stage.

3. How does the pricing approach differ between a test batch and a series?
A test batch is usually more expensive per unit: part of the setup and tooling costs is spread over a small volume. In a series, these costs are spread over a larger number of products, and the unit price decreases.

4. Can the design be changed after the series has started?
Yes, but this requires revising the process and price. Therefore, it is better to incorporate and work through major changes at the prototype and test batch stages.

5. What if demand grows faster than planned?
You need to revise the production schedule, batch sizes, and, if necessary, tooling. With early notification, it is easier to adjust production without missing deadlines.

6. How is quality controlled in contract manufacturing?
At the test batch stage, control criteria are agreed upon: geometry, weld quality, coating, packaging. In the series, these criteria are fixed in process sheets and checklists.

7. Can different products be combined in one series (for example, frames and mounts for solar/PV)?
Yes, if they are technologically compatible in terms of material, thickness, and operations. This is discussed during production planning and can help optimize equipment utilization.

8. Who is responsible for installing finished metal structures?
There are several options: supply of products only, supply with supervision of installation, or full turnkey installation. The format is agreed at the TS stage and affects the overall budget and timing.

What happens if you change nothing and continue “one-off” production

• The new product “takes away” capacity from the core business.
• Launch timelines stretch out, and competitors reach the market earlier.
• Unit cost remains high due to the lack of a serial approach.
• Any design refinement turns into a separate project rather than a manageable stage of the cycle.

Contract manufacturing allows you to break this pattern: you focus on the product, market, and sales, while a partner who works with metal every day takes over production.

How to transfer a project to BRIX.UZ: what data is needed for calculation and launch

To move from idea to a real “prototype — test — series” cycle, it is important to start correctly.

Step 1. Submit a request for calculation
In the request, specify basic information about the product and planned volumes.

Step 2. Prepare the TS for calculation
For a prompt and accurate calculation based on the TS, prepare:

• product purpose and operating conditions (outdoors/indoors, temperature, humidity, food contact, etc.);
• dimensions and an approximate scheme/sketch (photo of a sketch, PDF, DWG, STEP — any available format);
• intended material (mild steel, galvanized steel, stainless steel), thickness;
• coating requirements (powder coating, color, presence of corporate colors);
• expected service life and loads (static, dynamic, one-time);
• planned volumes: prototype, test batch, series (pcs/month or pcs/year);
• installation requirements: whether on-site assembly is needed, site specifics;
• desired timing for receiving the prototype and starting the series;
• city/region of delivery (Tashkent or other regions of Uzbekistan).

Step 3. Jointly build the “prototype — test — series” cycle
Based on the TS, a proposal is formed for technology, timing, and stages. Then comes sequential implementation: prototype, test batch, series.

Submit a request for calculation

Hand the project over for execution while your competitors are still just discussing ideas. Fill out the request, attach available materials (sketches, drawings, photos), and specify:

• contact details (full name, company, phone, e-mail);
• a brief description of the product and its application area;
• dimensions and approximate material;
• planned volumes (prototype / test / series);
• coating and installation requirements;
• desired launch timing.

After that, you can move on to a substantive discussion of technology, timing, and budget specifically for your project.
