Depending on the product, manufacturing may involve die-casting, stamping, CNC machining, polishing, assembly, PVD coating, electroplating, or other finishing processes.

The specific sequence depends on the product structure and the selected manufacturing and finishing methods.

4. Quality Inspection

In-process checks are carried out at relevant manufacturing stages. Final inspection may cover dimensions, appearance, color, assembly, and functionality according to the agreed specifications.

Additional tests or third-party inspections can be arranged where required and agreed for the project.

5. Packing and Shipment

Finished products are packed according to the confirmed packaging requirements. Shipping documents, such as commercial invoices and packing lists, are prepared as applicable.

Shipment arrangements and tracking information are provided according to the agreed logistics service.

Customers can confirm the expected production milestones and communication arrangements with our team when placing the order.

Sample development time depends on the product design, manufacturing process, material, surface finish, and whether new tooling is required.

Stock Hardware with Custom Logos

For selected in-stock products requiring laser-engraved logos, samples can generally be prepared in 5–7 days, subject to stock availability and customization requirements.

Customized Products Using Existing Tooling

For customized products that can be manufactured using existing tooling, sample development generally takes around 20–25 days, depending on the product and finishing requirements.

Products Requiring New Molds

For products requiring new mold development, the sample development process generally takes around 30–35 days. This includes the relevant tooling, trial production, and sample finishing stages, subject to the project's complexity.

Complex mechanisms or special finishing requirements may require additional time.

Design Review and Prototype Evaluation

Technical drawings or 3D CAD models may be prepared during the initial development stage, depending on the information provided and the project's complexity.

Where useful, a preliminary prototype may be considered to assess dimensions or appearance before final metal tooling is produced. Prototype methods and timing are confirmed separately.

Sample Delivery

The times above refer to sample preparation and development, not international shipping. Courier transit time should be added when calculating the date the sample will arrive at the customer's location.

A project-specific schedule can be provided once the design, material, finish, and tooling requirements are confirmed.

Yes. Customers can develop and evaluate samples before deciding whether to proceed with mass production.

Stock Samples

For selected in-stock products, samples with laser-engraved logos can generally be prepared in 5–7 days, depending on stock availability, logo requirements, and the finishing process.

Customized Samples

For customized products, sample development time varies according to the material, structure, manufacturing method, surface finish, and whether new tooling is required.

Where a new mold is needed, mold development and trial production will affect the sample schedule.

Sample Evaluation

Samples allow customers to review dimensions, appearance, logo placement, color, assembly, and functionality before mass production.

Additional testing can be discussed when the product has specific mechanical, coating, or compliance requirements.

Sample and Tooling Costs

Sample charges and tooling costs depend on the project. Any credit or refund of these charges against a future bulk order must be confirmed in the quotation or commercial agreement.

Sample approval does not automatically require a bulk order unless otherwise agreed. Customers can use the sample evaluation stage to determine whether the product meets their requirements before making a production commitment.

Starting a project with Carosung involves a series of steps designed to clarify requirements, assess manufacturability, and confirm the product before mass production.

Step 1: Share Your Requirements

Customers can provide reference images, sketches, technical drawings, 3D CAD files, existing samples, or a description of the intended product.

Helpful information includes:

Product dimensions and functional requirements.

Preferred material and surface finish.

Logo application requirements.

Estimated order quantity.

Target budget and delivery schedule.

Packaging and destination market requirements, where applicable.

Step 2: Technical Review

Our team reviews the available information and assesses the design's manufacturing feasibility. Where necessary, we may request additional dimensions, clarify the intended function, or recommend design adjustments.

The time needed for this stage depends on the completeness of the information and the complexity of the project.

Step 3: Quotation and Sample Development

Once the requirements are sufficiently clear, we provide a quotation covering applicable tooling costs, sample charges, unit prices, estimated lead times, and other agreed requirements.

Samples are developed according to the product type and project scope. For new designs, tooling may be required before a finished metal sample can be produced.

Step 4: Sample Approval and Order Confirmation

Customers review the sample and confirm the required appearance, dimensions, function, and other agreed specifications.

Mass production proceeds after the relevant sample approval, order confirmation, and agreed payment arrangements.

Step 5: Production and Shipment

During production, quality inspections are conducted according to the agreed requirements. Finished products are packed and shipped using the selected logistics arrangements.

Shipping terms, such as FOB, CIF, or DDP, can be discussed according to the destination, order requirements, and agreed commercial conditions.

Carosung offers different minimum order quantities depending on whether the product is available from stock or requires customization.

Stock Hardware

The standard MOQ for selected stock hardware is 50 pieces per design, subject to stock availability and product requirements.

Selected stock items may also be customized with laser-engraved logos, depending on the product and logo design.

Customized Stainless Steel Hardware

The standard MOQ for customized stainless steel products is 200 pieces per design, subject to the product structure, manufacturing method, and finishing requirements.

Customized Zinc Alloy Hardware

The standard MOQ for customized zinc alloy products is 500 pieces per design, depending on the mold, structure, and production requirements.

Complex or Special Designs

Products with complex mechanisms, multiple components, special materials, or demanding finishing requirements may require a different MOQ. These projects are evaluated individually.

Pricing and Multiple Finishes

Unit prices generally vary according to order quantity, material, manufacturing process, surface finish, and packaging requirements.

For projects requiring multiple colors or finishes, the feasibility and minimum quantity for each finish should be confirmed separately. Using the same mold may avoid the need for an additional mold, but other finishing or production charges may still apply.

Contact us with your design, estimated quantity, and preferred finish for a project-specific quotation.

Color consistency is managed through surface preparation, process control, approved reference samples, and appropriate inspection methods.

Surface Preparation and Process Control

Polishing and other surface preparation steps influence the appearance of the finished hardware. Consistent preparation helps reduce visible differences caused by surface roughness, scratches, or uneven reflections.

For PVD coating, relevant process parameters are controlled according to the coating system and equipment. For electroplating, factors such as bath chemistry, process conditions, and finishing steps influence the final color and appearance.

Approved Color Samples

Before mass production, customers can approve a physical sample representing the desired finish. This sample can then serve as a reference for production and subsequent orders.

For repeat orders, retaining approved samples and production records helps compare the appearance of new batches with the previously accepted finish.

Managing Repeat Orders

Different production batches may show some variation because of differences in materials, surface preparation, or processing conditions. Our aim is to maintain consistency with the approved reference sample and the agreed acceptance criteria.

For particularly color-sensitive projects, customers should confirm the master sample, acceptable color variation, and inspection method before mass production.
