Through our rich experience and perfect supply chain, our company can provide customers with high-quality customized custom design shoe 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 custom design shoe parts moulding products, we can make corresponding plastic parts, which is mainly done through injection molds.

The customization of plastic parts for shoes (such as soles, heels, and decorative pieces) is a specialized field that integrates ergonomics, materials science, and precision manufacturing. The core point is that parts are not only "structural components", but also "functional components" that directly determine the wearing experience. Its customization process can be summarized into the following key stages:

�� First stage: Clarify requirements and functional definitions

First of all, it is necessary to clarify the purpose of the parts, which directly determines the selection of all subsequent designs.

Core function: Does it need to serve as a buffer, support, anti-slip or decorative function? For instance, the midsoles of sports shoes emphasize shock absorption and rebound, while the toe caps of safety shoes require high-strength impact resistance.

The suitable object: Is it shoes for one-piece molding through injection molding (i.e., the sole and the upper are combined through injection molding), or is it used as a component to bond with other materials (such as textile uppers)?

Performance standards: What physical property tests need to be met? For instance, the overall flexing performance of the shoe (testing the bending life of the sole), the wear resistance of the outsole, and the anti-slip performance (especially the anti-slip performance in wet conditions) are all key assessment indicators.

✍️ Phase 2:3D design and mold engineering

This is the core stage of transforming concepts into producible molds. The curved surface modeling of shoe parts makes its design particularly special.

Data collection and modeling: Usually starting from shoe lasts or design models. Modern design often combines 3D scanning to obtain precise surface data and then uses CAD software for modeling. For complex surfaces, the combination of forward and reverse modeling is a common approach.

Shoe model specialized design: Shoe model design is highly professional.

Parting surface design: It should be carried out along the most inconspicuous and easily demolding direction of the sole's curved surface, which directly affects the appearance of the product and the difficulty of demolding.

Runner and exhaust system: The design of the feed port (gate) position must ensure that the plastic can fill the entire cavity evenly and quickly, and avoid defects caused by trapped air. Poor exhaust can cause the product to be underfilled or scorched.

Shrinkage compensation: Different plastics (especially foamed materials such as EVA) have different shrinkage rates. Shrinkage compensation must be carried out in advance during design to ensure the accuracy of the final dimensions.

Prototype verification: Before opening a formal steel model, a physical model is often made using substitute wood (a type of model material) or 3D printing to confirm the shape, feel and assembly relationship.

�� third stage: material selection and process matching

The materials of shoe parts directly determine performance and cost, and must be perfectly matched with the process.

Common shoe plastics: mainly include TPR (thermoplastic elastomer), EVA (ethylene-vinyl acetate copolymer), PU (polyurethane), PVC (polyvinyl chloride), and rubber (RB), etc. When making a choice, it is necessary to weigh softness, elasticity, density, wear resistance, yellowing resistance and cost.

Process matching: Different materials correspond to different processes. For instance, mold injection molding (also known as turntable injection molding) is an efficient process in which the sole and the upper are formed in one go. The cold bonding process involves first injection-molding the sole and then bonding it to the upper. It has very high requirements for the bonding strength of the upper and sole (for example, the standard requirement is ≥ 1.4N /mm).

�� Phase 4: Mold manufacturing and trial mold

Molds are the core assets of customization, and their quality determines the precision of the product.

Precision processing: The cavity of the shoe model is complex, and processes such as CNC fine engraving need to be adopted to replicate fine patterns and textures. The surface of the mold may need to undergo embossing treatment to create a specific anti-slip or decorative texture on the product.

Mold testing and debugging: This is a crucial link connecting design and mass production. Through mold testing, process parameters such as temperature, pressure, injection speed and cooling time are adjusted to solve possible problems such as material shortage, shrinkage, weld marks and warping deformation. Sample samples need to undergo comprehensive verification in terms of size, appearance and function.

✅ Phase 5: mass production and quality control

Stable mass production requires strict process control and standardized inspection.

Process stability: In mass production, it is necessary to continuously monitor and maintain the stability of process parameters to ensure the consistency of each batch of products.

Comprehensive quality inspection: In addition to routine size checks, physical property tests must be conducted on finished shoes or components in accordance with relevant standards (such as HG/T 3084-2023 "Injection Molded Shoes"). This includes but is not limited to flex tests, wear resistance tests, peel strength tests, cold resistance tests, etc., to ensure that they meet the design life and safety requirements.

Core advice from �� for you

The key to success lies in the highly specialized customization of shoe parts:

Cooperate with professional shoe mold factories and supporting factories: They have experience in handling complex curved surfaces and are familiar with the characteristics of shoe materials, and can provide full-process solutions from design optimization to mass production.

Attach great importance to physical sample making: Any design must undergo long-term and multi-scenario fitting tests through physical sample shoes to verify its comfort, durability and safety. This is a step that 3D models cannot replace.
