Can you produce components with a high-gloss finish?

Yes, the state-of-the-art technologies we employ, together with polishing methods and ideal molding parameters will help us in obtaining high gloss on parts. The grade of steel used for making the molds, along with the fine-grit sandpaper for polishing, gives a mirror-like smooth surface finish on the molded parts.

What measures are taken to prevent defects like warping, cracks, and air bubbles?

To prevent possible defects, we are making the injection molding process parameters optimum such as temperature, pressure, and cooling time. The mold design also is very important with the gate location placement, the feed system design, and the cooling channel layout being what ensured the consistent flow of materials and cooling. Moreover, we mend regularly the molds as one tidy aftermath of such a process may cause problems.

How do you ensure the components fit perfectly when assembled?

The perfect fit during the assembly is indeed achieved by a specific mold design and by compliance with tight tolerances as well during the manufacturing process. Additionally, we run assembly tests of the very first production sheets to find out any possible issues and do corrections to the molds or process parameters accordingly.

What is the typical lead time for producing luggage scale components?

The lead time can be variable, depending on the complications of the components, the mold design, and the order quantity. Generally, the cycle time is between 4 and 6 weeks after the mold is finished, which consists of the initial manufacturing run. We strive to maintain collaboration with our clients in determining a schedule that aligns with their projects.

For this project, the injection molding of components of airport luggage scale part was involved. Notwithstanding such simplicity of structure, the project did present some small challenges including large edge radiuses and high-gloss surface finish.

Small Challenges

Large Edge Radii: The design was very complex and involved great edge radii which were often the cause of 결함 like warping or tearing.

High-Gloss Surface Finish: Raising and restoring the gloss of the component surfaces was the most difficult step of all and needed very precise mold polishing using sandpaper with 12000 grit.

Precise Assembly: The design of the product required two parts of the assembly, accurate alignment and consistent seam at the seam.

Injection Molding and Mold Design

1×4 Mold Structure: In order to enable mass production, a 1×4 machinery layout which allows per minute production of 480 units has been chosen without jeopardizing the quality.

Mold Polishing: Molds were very carefully polished with 12000 grit sandpaper to reach a key high-gloss on the parts. A process that requires a lot of precision and skill so no defects happen.

Seamless Integration: Also, the mold design was modified in order to make the assembly of the two components very accurate so that there was no gap and the part met the required quality.

결과

The client was impressed low-cost parts from FirstMold not only fulfilled but surpassed the expectations in terms of function, aesthetics, and accuracy. The innovative way we designed molds and the total control we had during the injection molding process enabled us to provide quality 대량 생산 meeting the highest industry standards.

Aesthetic Requirements:

1. The surface of the product must be free from whitening, cracks, warping, burrs, weld lines, bubbles, or flash.
2. Silk-screen printing must be clear, without any breaks, color discrepancies, or peeling.

성능 요구 사항:

1. The outer shell must not produce any abnormal noise when pressed or squeezed.
2. All specifications, dimensions, and materials must adhere to the provided drawings and Bill of Materials (BOM).
