Wintech Mold from Order to Shipment Process
The creation of a qualified mold requires multiple rigorous processes, including demand analysis, solution design, processing and manufacturing, mold trial verification, and delivery. Each step directly affects the mold quality and the final product molding effect. Below, we will introduce the complete ordering process for Wintech molds:
1. Customer Order and Demand Confirmation
Upon receiving a customer order, the technical team reviews the product drawings, samples, production requirements, materials, and output, conducts a Design for Product Development (DFM) to assess project feasibility, clarifies mold specifications and delivery timelines, finalizes cooperation details, and officially launches the mold project.
2. Mold Solution and Structural Design
Based on the customer's product data, mold design work is carried out, completing the structural planning for parting lines, gates, cooling systems, and ejection systems, and outputting 2D assembly drawings and 3D mold models. The design solution is simultaneously confirmed with the customer, and after confirmation, the manufacturing phase begins.
3. Raw Material Procurement and Preparation
According to the design drawings, mold steel and standard accessories are selected, and mold plates, guide pillars and bushings, springs, inserts, and other materials are procured. The steel is inspected to ensure that the material hardness and performance meet production conditions, completing material preparation.
4. Mold Machining and Manufacturing
This involves machining mold components, including roughing of steel, CNC milling, EDM, wire cutting, drilling and tapping, grinding and polishing, etc. Core components such as the mold core, mold base, slider, and inserts are machined, achieving precision machining for each part.
5. Mold Assembly
All machined components are assembled using a fitter's technique. Components such as the mold core, slider, ejector mechanism, and cooling pipes are assembled and installed. The clearances between components are adjusted, and the smoothness of the moving parts is checked, completing the final mold assembly.
6. Trial Molding, Debugging, and Optimization
After assembly, the mold is tested on the injection molding machine to produce sample parts. The dimensions, appearance, and structure of the samples are checked to ensure they meet customer standards. For issues such as flash, shrinkage, and dimensional deviations, the mold is repaired, ground, and adjusted. Repeated trial molding is conducted until the sample fully meets the customer's technical requirements.
7. Mold Inspection and Testing
After sample confirmation, a comprehensive final inspection of the entire mold is conducted: checking the mold opening and closing motion, cooling water channels, clamping structure, and the integrity of accessories; verifying mold drawing parameters; identifying potential fault points; and performing rust prevention treatment.
8. Packaging and Delivery
After the mold passes inspection, mold drawings, accessory lists, user manuals, and other supporting documents are prepared. Rust prevention measures are taken, the mold is packaged, and logistics are arranged for delivery to the customer. Simultaneously, technical support related to the subsequent use and maintenance of the mold is provided.

What Is Plastic Injection Molding?
Plastic injection molding is the most prevalent and efficient industrial manufacturing process for producing custom plastic parts, serving as the cornerstone of the global plastic processing industry. It is a cyclic manufacturing technology that enables the mass production of high-precision, complex-shaped plastic components with consistent quality. Widely adopted across automotive, medical devices, consumer electronics, packaging and household product industries, this process accounts for over 70% of all plastic finished parts in industrial manufacturing.
In short, plastic injection molding is a molding method that converts solid plastic raw materials into finished products through melting, injection, cooling and shaping. The complete working principle follows a fixed cyclic logic: solid plastic pellets are fed into the heating barrel of an injection molding machine, heated and plasticized into a uniform molten state. Under the thrust of a screw or plunger, the molten plastic is injected into a closed precise mold cavity at high pressure. After heat dissipation, cooling and curing, the plastic solidifies into a fixed shape matching the mold cavity, and the finished product is finally ejected by the mold opening mechanism.The process is mainly applicable to thermoplastics such as PP, ABS, PC, nylon and PET, as well as a small number of thermosetting plastics. It requires raw materials with good fluidity to ensure full filling of the mold cavity and eliminate product defects such as missing material and shrinkage.
Five Core Production Stages
First is clamping. The clamping unit of the injection molding machine tightly closes and locks the mold to withstand the high pressure generated during injection and prevent mold expansion and product deformation.
Second is injection and filling. The molten plastic is quickly injected into the mold cavity until the cavity is nearly fully filled.
Third is packing and holding. Continuous pressure is applied to compact the molten plastic, compensate for volume shrinkage caused by cooling, and ensure dense product structure and stable size.
Fourth is cooling and curing. The cooling water circulation system inside the mold continuously dissipates heat to solidify the plastic parts, which is the longest link in the molding cycle.
Fifth is ejection and demolding. After the parts are fully shaped, the mold opens, and the ejection system pushes the finished plastic parts out of the mold to complete a production cycle.
Plastic injection molding covers almost all fields of industrial and civilian plastic products. In the automotive industry, it is used to produce interior trim parts, bumpers, instrument panels and lightweight structural parts. In the medical industry, it manufactures disposable medical supplies, precision instrument shells and sterile plastic parts that meet medical standards.

Origin of the Qixi Festival
Qixi comes from the ancient legend of Niulang and Zhinv.
Niulang, a cowherd on earth, fell in love with Zhinv, a weaving fairy from heaven. They got married and raised two kids.
However, the Goddess of Heaven forbade their love. She pulled out a silver hairpin and drew the Milky Way, forever separating the two lovers.
Moved by their true love, thousands of magpies fly each year to build a magpie‑bridge. The couple can meet only once a year, on the 7th day of the 7th lunar month.
Later, people turned this day into the Qixi Festival, now regarded as China’s Valentine’s Day.
In ancient times, young women prayed to the Weaver‑Fairy for craft skills and happy marriages. They competed in needle‑threading games, made offerings of fruit and watched the stars at night.
Nowadays, Qixi is celebrated as Chinese Valentine’s Day. Lovers give gifts, enjoy dates and show their affection to each other.
