Plastic injection Molding
We provide high-quality injection parts on demand. Injection molding is the most cost-effective method for mass production of plastic parts and provides consistent quality for small to large volumes. Compared with CNC machining and even 3D printing, molding also has the most materials, colors and configurations.
Our plastic injection molding process produces custom prototypes and end-use production parts in 15 days or less. We use aluminum molds that offer cost-efficient tooling and accelerated manufacturing cycles, and stock more than 100 different thermoplastic resins.
In this process, melt the resin under high pressure into the cavity of the metal mold to form the desired mold shape. After cooling the mold, get the desired product shape. A single cycle to make a finished part may take anywhere from a few seconds to minutes depending on part complexity and size.
At Hua-pin, we offer rapid tooling, mold making, and die manufacturing for both low-volume production, mass production, and prototyping. Our expertise includes steel, and aluminum tooling, and mold maintenance, redesign services.
Over molding is a process used to combine at least two materials into one project. At Hua-pin, we can mold a thermoplastic material into a second material to leverage certain performance and characteristic attributes of the materials to complement functionality.
Overmolding is very effective for manufacturing composite parts, and its cost is lower than other production techniques that require the assembly of individual parts. Over molded parts typically consist of a substrate and the over molding material. Substrate material include metal,plastic,glass and more.
What is insert molding? The resin is injected into the mold after the pre-prepared insert of different materials, and the fused material is bonded and solidified with the insert to make the molding method of integrated products.
Through our expertise in cross-technology fabrication, we can use sheet metal and CNC machining to make units of your metal part and employ insert molding to introduce plastic parts. Insert molding can be used in making tools that are sharp and require a grip.
What is Plastic Injection Molding
Plastic injection molding is by far the most common way to produce large volumes of finished plastic parts for every kind of commercial and industrial use.
Molten resin is injected under high pressure into the cavity of a metal die and then rapidly cooled, forming a solid shape. A single cycle to make a finished part may take anywhere from a few seconds to minutes depending on part complexity and size.Plastic injection molding is a manufacturing process where resin in a barrel is heated to a molten state, then shot into a mold to form a final production-grade thermoplastic part.
Advantage of Plastic Injection Molding With Huapin
1.Production cost: Compared to other processes, the price of each piece through injection molding is significantly lower, especially as the number of survivors increases to several thousand.
2.Precise dimension：The mold can be machined by CNC with high precision, with tolerances up to the national standard GB/T 14486-2008, and is capable of producing thousands of identical parts.
3.Part quality: Under the condition of the same material and parts, the performance of molded parts is generally better than that of parts produced by other processes.
4.Material diversity: Choose from hundreds of manufacturing materials including various grades of thermoplastics, metals, and elastomers.
