Custom PFA/PVDF/FEP Injection Molding

PFA injection molding technology and process is a special fluoroplastic molding solution tailored for high purity, high corrosion resistance and high stability requirements. Its core lies in dedicated mold design, strict process control and a clean production system.

This technology is widely applied in semiconductor high-purity fluid pipe fittings, valve bodies, joints, nozzles and chemical corrosion-resistant components. It can deliver highly reliable results from structural design, mold development to stable mass production, meeting the stringent requirements of high-end industries for purity, performance and long-term stability.

Molding and Mass Production

Through multiple rounds of mold trials (T1, T2, etc.), we verify the mold performance, adjust details such as gates and cooling systems, and ensure that the final product quality meets standards while optimizing production efficiency. We strive to meet customer requirements to the greatest extent possible.

Ultrapure Water Cleaning

Ultrapure water cleaning is a crucial step in producing our high-purity PFA injection molded products. By leveraging the high purity and low impurity characteristics of ultrapure water, it effectively removes tiny particles, ions, organic matter, and other impurities from the product, ensuring the product’s purity.

Steps to produce PFA/PVDF/FEP molded products

High-purity PFA molded products are highly favored for their excellent corrosion resistance, high-temperature stability, and low permeability. From product design to shipment, the production process of PFA molded products is rigorous and precise, ensuring the outstanding quality of the products.

/01 Product Design

During this stage, engineers carefully design the fittings based on customer needs and usage environment, taking into account factors such as size, shape, pressure rating, and connection method. The design process not only aims to meet functional requirements but also ensures the product's aesthetics and ease of use. With the help of advanced CAD software, engineers can simulate a 3D model of the fitting, providing accurate data support for subsequent mold design and manufacturing.

/02 Mold Design

Molds are key tools in the production of high-purity PFA fittings, and their design quality directly affects the precision and surface quality of the products. Designers carefully calculate the various dimensions and parameters of the mold based on the product design drawings to ensure that the mold can accurately replicate the shape and features of the product. At the same time, they also consider details such as mold material selection, processing technology, and ejection methods to ensure the durability and production efficiency of the mold.

/03 Mold Machining and Manufacturing

The mold manufacturing stage is the process of converting design drawings into physical molds. Using high-precision CNC machines and advanced processing techniques, technicians precisely machine the various components of the mold, assemble and debug them. Additionally, since PFA produces corrosive gases during injection molding, the mold needs to be made from special steel. Strict quality control during this process is crucial to ensure the quality of the mold.

/04 Mold Trial

The mold trial stage is an important part of verifying the mold in practice. Through mold trials, we can check whether the mold's molding effect, product size, and surface quality meet the design requirements. Furthermore, during the mold trial, we can optimize the production process to improve the product's purity. If there are any issues, appropriate adjustments need to be made to the mold components to ensure that the mold can produce qualified products.

/05 Mass Production

After the mold trial is completed, we will carry out mass production in a Class 1000 cleanroom. We have a professional production team, a clean production environment, and advanced production equipment, which not only improves production efficiency but also ensures product quality, ensuring that the products can meet customers' stringent technical requirements and produce products that are magnified hundreds of times without black spots.

/05 Quality Inspection and Shipment

After the production of the products is completed, we will further remove impurities adhering to the product surface by cleaning them with ultrapure water and drying them. Then, the products are sent to a Class 100 cleanroom, where we will conduct product inspection, assembly, and packaging for shipment. Only then can Derong Yuandao high-purity PFA fittings be considered complete. Afterwards, we will also provide after-sales support and improve our products based on customer feedback.
