Learn about Lianyu
Chengdu Lianyu Precision Machinery Co., Ltd. was established in May 2005, reformed from the original Chengdu Lianyu Precision Machinery Processing Factory (established in 1997). It is the first enterprise in Sichuan Province to specialize in the research and development (food/beverage packaging, medical), customized production of injection molding machines, and OEM production of plastic products (beverage packaging materials/medical consumables). It is also a major production base enterprise in our province for the research and development and production of food and medical mold products, playing a significant role in technological innovation and demonstration.
Since its establishment, through more than 20 years of continuous exploration and innovation, the company has the technical strength to produce more than 20,000 cavities of various molds annually. Its partners are spread throughout the country, and it continuously provides high-quality and reliable injection molding packaging services to partners in many countries and regions around the world.
Quality
We independently realize all key process flows—except for surface treatment, all mold product processes are completed in-house, with strict quality management. We have a rich supply chain system, reliable quality, good value for money, and quick feedback.
Innovation
The harvest of multiple patents represents our innovative spirit. Together with you, we develop more modern solutions for plastic product production—from product design to mass production, we are your reliable helper.

28 years of continuous innovation
Since our establishment in 1997, we have been a representative research and development enterprise in Southwest China, ranging from mold component processing and complete mold manufacturing to the production of customized injection molding machines on a considerable scale. With our extensive experience and achievements, you can confidently entrust your products to us.
Process Closed Loop
Over 95% of the processes are completed within the factory
We firmly believe that having complete control over every aspect of the manufacturing process is the greatest responsibility we have to our clients' products. To this end, we have invested heavily in personnel and resources to build our own metal material cold/hot treatment workshop, achieving a complete in-house closed-loop system for mold part processing and inspection, excluding surface chemical treatment.
Talent cultivation
Designers rooted in the production line
Most of our designers, even the company management and chairman, are selected and cultivated from the production line. They have at least two months of practical production experience in each processing procedure. We believe that designers who understand equipment parameters and production processes can bring more stable product structures and reasonable processing technologies.
Standardized Management
Everything is done according to the "standard".
Our standardized management model, implemented consistently for many years, encompasses design specifications from the initial design proposal stage, stringent selection of raw materials and components throughout the supply chain, and standardized processes in production. The consistency resulting from these high standards ensures that Lianyu products exhibit exceptional reliability and durability.

Injection molding, blow molding, and canning "One-step" preform production system
We pioneered the integrated PP infusion bottle hanger mold solution and obtained a national invention patent in 2016. This solution successfully eliminated the need for "manual welding of hangers" in the past process, significantly reducing time and labor costs. This laid the foundation for Lianyu's subsequent dominance in the medical infusion mold field.

Five major processes for precision mechanical parts processing
Generally, the processing and production are targeted at components of precision machinery and equipment. This requires a very high degree of accuracy. Therefore, in addition to understanding the specific material requirements for precision machinery parts processing and the common techniques for precision machinery component processing, we should also understand the processing steps involved in precision machinery component processing. Below, we share the five stages of precision machinery parts processing.

What is mechanical manufacturing? What is the nature of the mechanical manufacturing industry?
Mechanical manufacturing comprises seven detailed industry segments, three of which manufacture machinery for specific sectors, known as special-purpose machinery: agricultural, construction and mining machinery manufacturing; industrial machinery manufacturing; and commercial and service machinery manufacturing.

What are the processing requirements for precision parts?
Generally, due to the different effects of cutting volume, heating, and cutting force on the roughness and precision of parts, rough parts and precision mechanical parts must be processed separately to ensure the machining accuracy of the parts. If initial processing and precision processing are continued, the precision of the precision-machined parts will be lost due to different stresses.

Development Prospects, Current Status, and Trends of the Machinery and Equipment Industry
The machinery industry is a typical discrete manufacturing industry, characterized by multi-variety and small-batch production; there are many types of products, the products are complex, and there are many uncertain factors affecting the production process. Emergency orders and equipment failures often occur, causing changes in production plans; the manufacturing process is complex, and there are many uncertain factors in the production process. Dispatching based on experience cannot guarantee the coordination of the entire production process, process control is difficult, and management is difficult.

Pay special attention during the mechanical design process
Pay special attention to the following points during mechanical design: 1. Kinematic calculation of the machine: Based on the determined structural scheme, determine the parameters of the prime mover (power, rated speed, conversion rate, etc.); then perform kinematic calculations to determine the motion parameters of each moving component (speed, linear velocity, acceleration, etc.).
