Keyboard custom parts moulding

In addition, our company has established cooperative relationships with plastic raw material suppliers, printing manufacturers, etc. to ensure the supply of raw materials and printing quality. Through our rich experience and perfect supply chain, our company can provide customers with high-quality customized keyboard custom parts moulding products to meet their specific needs. At the same time, we have 10 years of professional foreign trade service experience, understand the foreign trade process, and better serve our customers. For keyboard custom parts moulding products, we can make corresponding plastic parts, which is mainly done through injection molds.

This is the stage of shaping the soul of the keyboard, far more than just drawing.

Core requirement communication

Layout and structure: Configuration (such as 65%, 75%, TKL), connection method (wired/three-mode), structure (Gasket mount, Top mount, etc.), these directly determine the internal structure design of the housing.

The goal of hand feel and sound adjustment: material selection (affecting sound), positioning plate design (affecting softness and hardness), all need to serve this purpose.

Appearance theme: Color scheme (Pantone color code), surface treatment (high gloss, matte, special coatings such as electrophoresis), theme elements (Logo, decorative strips).

Industrial Design and Structural Design

Exterior design: Complete the ID renderings and determine the styling language and texture.

Structural design: Disassemble the parts and design all the clips, screw columns, reinforcing ribs, positioning columns, battery compartments, etc. This is the stage that tests engineering capabilities the most, directly affecting the smoothness of assembly and structural strength.

DFM Analysis and Materials Science Selection

Keycap

Material: ABS (smooth to the touch, easy to oil) or PBT (wear-resistant, strong granular feel, heat-resistant).

Key points of DFM: The design of reinforcing ribs prevents deformation, the size of the chrysanthemum-shaped columns is precise, and the wall thickness is uniform.

Shell

Materials: ABS (easy to spray), PC (high strength and high transparency), nylon (high-end, silent, extremely high strength).

Key points of DFM: Prevent shrinkage and warping of large flat surfaces; Fit tolerance design of the snap; Reserve the thickness of the spray/electroplating film.

Positioning plate

Materials: PC (soft and elastic), POM (brittle), FR4 (fiberglass board, non-injection molded), steel/aluminum (non-injection molded).

Key points of DFM: Shaft hole position accuracy (within ±0.05mm), rigidity guarantee.

Phase Two: Precision Mold Manufacturing

Molds are at the core of determining the final quality and cost efficiency.

Keycap mold

Ultra-high precision and multi-cavity: Ten or even hundreds of cavities in one module. Process chrysanthemum-shaped columns using a precision EDM machine.

Character processing: Regular engraved characters need to be laser-engraved or chemically etched on molds. Side engraving requires precise processing on the side of the mold.

Shell mold

Large and complex molds: Usually, multiple sliders are required to handle side overhangs and interfaces.

Ultimate surface treatment: The cavity needs to be mirror-polished or finely textured (such as coarse sand or fine sand texture) to achieve the desired touch.

Mold flow analysis: It must be carried out on keycaps and housings to predict filling, optimize gates (such as the commonly used bottom center point gate for keycaps), and prevent warping.

Phase Three: Injection Molding and Secondary Processing

Key points of injection molding process

Material drying: PBT, nylon and other materials must be strictly dried.

High mold temperature: Especially for PBT keycaps and PC housings, high mold temperature can reduce internal stress, improve dimensional stability and surface texture.

Secondary processing (the soul)

Keycap

Laser-engraved characters: Characters are engraved on the injection-molded keycaps and then filled with ink.

Two-color molding: Using two-color molds to produce characters that never wear out, it is costly and of top quality.

UV printing: Used for complex patterns.

Shell

Spraying: matte, glossy, metallic paint, etc.

Electroplating/anodizing (if the substrate is ABS+ electroplated grade or metal).

Water transfer printing /IMD: Achieve complex patterns such as wood grain and carbon fiber.

Phase Four: Full-chain quality inspection and assembly verification

This is the final hurdle to ensure a "ready-to-use" experience, and the customized keyboard has strict requirements for this.

Dimensional accuracy inspection

Keycaps: Use a dedicated inspection tool to measure the tightness of the Daisy column and the gap between the keycaps.

The shell: Use a three-coordinate measuring instrument to check the position, flatness and shape and position tolerance of the installation column.

Positioning plate: Detects the positional accuracy of all shaft holes to ensure perfect alignment with the PCB.

Appearance and texture inspection

Under standard light sources, 100% inspect the color difference, defects and water outlet treatment marks of the housing and keycaps.

Functional assembly testing (crucial)

Trial assembly: Assemble the entire set including the housing, positioning plate, PCB, shaft body and keycap.

Test item

Structural stability: Whether there is any shaking or abnormal noise.

Key consistency: Whether all key positions are smooth and if there are any stuck keys.

Soft and bouncy feel (if it is a Gasket structure) : Whether it is uniform.

Three-mode connection: Wireless connection stability.

Phase Five: Packaging and Delivery

Protective packaging: Customized inner supports made of EVA/ sponge are used to prevent scratches on the high-gloss surface during transportation.

Documents: Provide product specification sheets and quality inspection reports.
