In modern fluid delivery systems, PVC pipe fittings have become core components in building drainage, industrial pipelines, agricultural irrigation, etc. due to their light weight, high strength, corrosion resistance, and low cost. As a key node in the pipeline network, the types of joints for PVC pipe fittings are constantly enriched.

In the field of plastic pipe fitting manufacturing, the design of injection molds directly affects production efficiency, material utilization and finished product quality. By optimizing mold design, companies can not only reduce unit costs, but also increase production capacity and yield. The following are three proven optimization strategies, combining industry cases and technical details to provide systematic solutions for cost control.

In the field of construction engineering, the drainage, wastewater, and vent (DWV) system is the "vein" of the building, and its design is directly related to the health safety and operational efficiency of the building. The performance of the PVC DWV fitting system is highly dependent on the precision and quality of mold manufacturing. This article will analyze the core design logic of the DWV fitting system from three dimensions and explore the technical challenges and innovation directions in the field of mold manufacturing.

PVC pipe fitting is an important part of building drainage system. Its quality and performance are directly related to the stability and safety of the whole system. Therefore, in the manufacturing process, we must strictly control every link to ensure the quality and reliability of the product. However, this process is not easy. We are faced with many challenges such as mold design complexity, material fluidity, dimensional stability, etc.

The formation of modern household water supply systems is inseparable from low-cost mass production. Whether it is metal or plastic pipes and accessories, they are inseparable from molds. Mold manufacturing is an efficient production method that can achieve mass production. Through molds, a large number of accessories with the same shape, size and precision can be quickly replicated, greatly improving production efficiency and meeting the needs of large-scale construction of water supply systems.

Stacked injection molds are different from ordinary injection molds.It is a special mold structure. The stack injection mold has a plurality of parting surfaces, and each parting surface can have one or more cavities.

Thin-wall plastic parts not only depend on the thickness of the plastic part, also on the flow length to thickness ratio of the plastic and the viscosity coefficient of the plastic. It can be divided into the following three situations:

Nowadays, various mature injection molding processes bring more creative space to designers and engineers. They can inspire their inspiration to enhance the appearance and ergonomics of the product.

Moulds are intermediate products in the production process. It is the tool used to produce the final product. Mold processing is one of the important ways of material forming. It has the advantages of high material utilization, easy production and high efficiency. Therefore, it is widely used in the production of automobile, machinery, electronics, aerospace industry and daily necessities.

The non-exterior surface of the plastic parts where the strength and stiffness are the weakest. We should be design stiffeners. Not only improves the plastic parts of the forces, increase the strength and rigidity of the plastic parts. And save material.

Large scale injection molds account for an increasing proportion of the entire mold output.Such as car bumpers, dashboards, TV housings, washing machine inner cylinders, TVs, air conditioning machine parts, tubs, barrels, turnover boxes and other large injection mold products.

Weld lines is an important factor affecting the quality of plastic parts.Under the same process conditions, the strength of the weld line area is only 10-92% of the original material, which seriously affects the normal use of the injection molded product.
