Taizhou Lingfei Mould & Plastic Technology Co., Ltd. specializes in the design, manufacture, and sales of molds for tricycles and four-wheelers, as well as the production of plastic products

Automotive parts molds are primarily categorized into four major types: stamping dies, injection molds, die-casting molds, and forging dies.
1. Stamping Dies: Used to produce body panels (e.g., doors, hoods) and structural components (e.g., frames) by forming sheet metal through processes like blanking, drawing, and bending. Their advantage lies in rapidly manufacturing complex curved parts, completing multiple operations in a single press stroke, offering high efficiency and low cost.
2. Injection Molds: Used to manufacture plastic interior components (dashboards, door panels) and exterior parts (bumpers, grilles). Plastic is melted under high temperature and pressure before being injected into the mold cavity. Advantages include the ability to form intricate shapes, high surface precision (high-gloss injection molding achieves seamless, high-shine finishes), and support for mass production.
3. Die-casting molds: Primarily used for aluminum and magnesium alloy components (e.g., engine housings), where molten metal is injected into cavities under high pressure. Key advantages include rapid forming of intricate structures.
4. Forging dies: Employed to manufacture high-strength metal parts (e.g., connecting rods, gears) through high-temperature plastic deformation, achieving dense microstructures. Key benefits include producing precision components capable of withstanding heavy loads, with service lives reaching hundreds of thousands of cycles, and high material utilization rates.

Tricycle molds are specialized tools used in the stamping process. In electric tricycle manufacturing, stamping dies are primarily employed to process metal sheets. Through the stamping action of the dies, the metal sheets undergo plastic deformation, yielding parts with the desired shape and dimensions. These parts undergo subsequent processing and are ultimately assembled into complete electric tricycle products. The operational principle of electric tricycle stamping dies relies primarily on the power transmission of the stamping press and the precise design of the dies. During the stamping process, the press delivers sufficient pressure to force the upper and lower dies together, stamping the metal sheet positioned between them. The complementary convex-concave structure of the dies causes the metal sheet to deform under pressure, thereby completing the part's fabrication.
Application Value of Electric Tricycle Stamping Dies:
Enhancing Production Efficiency: Stamping dies enable rapid and precise processing of metal sheets.
Ensuring Product Quality: Precisely designed dies guarantee consistent part shape and dimensions, thereby safeguarding the overall quality of electric tricycles.
Reducing Production Costs: The stamping process offers advantages such as high material utilization and low energy consumption, contributing to lower production costs for electric tricycles.

Two-wheeled vehicle molds: Primarily designed for motorcycles, electric bikes, and similar transportation vehicles.
Key advantages include: High efficiency and automation levels enabling continuous production of multiple components. Complex structures such as plastic housings and frame parts can be molded within tens of seconds to minutes, meeting mass production demands.
Strict precision control requirements, versatile production capabilities, and environmental sustainability—characterized by low energy consumption—align with green manufacturing standards.

The classification of plastic molds centers on forming processes, with different molds tailored to distinct product characteristics and production requirements.
High Forming Efficiency: Utilizes multi-cavity modular design, enabling simultaneous molding of 2-16 cavities for small parts. Achieves the shortest cycle time per product, meeting high-volume production demands.
Strict Precision Control: Constructed from high-precision mold steels like S136 and 718H, processed via five-axis CNC machining centers. Dimensional tolerances are controllable to satisfy precision component assembly requirements.
Broad Material Compatibility: Compatible with nearly all thermoplastics including PP, ABS, PC, PA66 + glass fiber, and TPE. Surface treatments (e.g., nitriding, chrome plating) optimized for modified materials enhance wear resistance by over 50%.

Injection molds: Plastic material is heated and injected into the mold cavity, then cooled and solidified to form the product. Its advantages include high precision, high efficiency, suitability for mass production, and the ability to produce complex plastic structures. It is primarily used in automotive components, home appliances, daily necessities, medical devices, and other fields to manufacture plastic shells, parts, containers, and similar products.
Compression Molds: Heated, softened plastic sheets or pellets are placed into the mold cavity, where pressure is applied to fill the cavity. After cooling and solidification, the finished product is formed. Advantages include fast production speed, relatively low cost, and smooth product surfaces. They are used to produce daily necessities like plastic cups, containers, boxes, as well as industrial components.
Stamping Dies: Utilizing presses and dies to process metal sheets into desired shapes and dimensions through multiple operations including blanking, bending, and drawing. Advantages include high production efficiency, precision, consistency, material utilization, and broad applicability. Primarily used in automotive manufacturing, home appliances, and electronics industries to produce body panels, refrigerator shells, mobile phone casings, and similar products.
Die Casting Molds: Molten metal is injected at high pressure and speed into mold cavities, solidifying upon cooling to form castings. This method offers high production efficiency, precise casting dimensions, and excellent surface quality. It is commonly used for automotive components and electronic device housings, such as engine blocks and transmission cases.
Mold Production: The process typically involves product analysis, structural design, material preparation and process planning, forming and heat treatment, assembly, and testing.
Mold Services: Cover the entire lifecycle from product design to post-sales support. This includes providing customers with mold design solutions optimized for product requirements; delivering timely progress updates and quality control during manufacturing; and offering post-delivery services such as installation, commissioning, training, maintenance, and repairs to resolve operational issues, ensuring consistent performance and extended mold lifespan.

The product range of daily-use molds is extensive, spanning multiple sectors including home goods, kitchenware, bathroom accessories, office supplies, and personal care items. Examples include plastic chairs and storage bins for home goods; lunch boxes and spice containers for kitchenware; toothbrush cups and soap dishes for bathroom accessories; file folders and pen holders for office and school supplies; and cosmetic cases and combs for personal care and consumer goods.
High Production Efficiency: Enables mass production by manufacturing multiple products simultaneously, shortening production cycles. Features like multi-cavity parallel molding in injection molds boost per-unit output.
Superior Product Quality: High mold precision ensures consistent dimensions and appearance across products. Capable of producing complex shapes and multi-functional structures to meet high-precision requirements for daily goods.
