SHENG WANG INDUSTRY──A Trusted Expert in Automotive Parts and Plastic Products

A custom plastic injection molding company founded in 1990, SHENG WANG MOLD & PLASTICS INDUSTRY CORP. specializes in the design, development, production, and assembly of automotive parts and various plastic products. We have a development and design department, allowing us to customize every stage. From product design and mold manufacturing to mass production and shipment, according to customer requirements, we’ll ensure the highest standards of product quality and functionality.
 ❖Our Process — From Development to Delivery 

1.  Requirement Confirmation：

Discuss with customer about their needs and analyze market trends to determine product functionality, appearance, and performance requirements.

2.  Appearance Design and Function Planning：
Create product sketches to define the appearance structure and functional layout.； Plan the functionality implementation based on the product's purpose and determine the core technical parameters.

3. 3D Modeling and Engineering Design：
Create precise 3D models using design software such as SolidWorks or AutoCAD； Ensure the product structure is robust, avoiding stress concentrations or interference in the design；
Conduct CAE (Computer-Aided Engineering) mold flow simulations to confirm the plastic's flowability in the mold and reduce potential issues such as shrinkage marks or air bubbles. 

4.  Mold Development, Manufacturing, and Mold Trial Adjustment：

Design the mold structure based on the product's 3D drawing, considering factors such as draft angles, runner design, and gate location； Select high-quality mold steel for CNC machining and surface treatment；
Manufacture the initial mold and conduct trial injection to verify mold accuracy and product quality. 

5.  Small Batch Production Trial and Function Testing：
Produce a small batch of samples for testing to evaluate the compatibility of the mold and production equipment；
Check the strength, dimensional accuracy, and surface quality of the samples to ensure they meet the design specifications；
Conduct real-vehicle or practical application testing to ensure stable and reliable installation and performance. 

6. Production Preparation：
Ensure that the settings of production equipment, such as the injection molding machine, are correctly configured；
Set up the production process for mass production, including parameters such as injection temperature, pressure, and cooling time；
Ensure the stability of raw material quality and maintain adequate inventory. 

7.  Mass Production：

Officially start mass production, monitoring the stability of injection molding and product quality；
Conduct inspection including dimensions, appearance, functionality, and durability test. 

8.  Assembly, Packaging, and Shipping：

Choose the appropriate packaging method based on customer requirements to ensure the product is undamaged during transportation；
Implement Warehouse Management System to accurately track the stock of each order；
Choose the best transportation method to ensure timely delivery.
