Technology Leader in Injection Molding

In many plastic mold forming methods, HingTung focuses herself only on the injection molding method for manufacturing plastic parts, with the aim of becoming the technology leader in this field, as injection molding method has the advantages of fast production speed, high efficiency, automatic operation, many color varieties, shape can be from simple to complex, size can be from large to small, and product size is accurate, products are easy to update and can become complex shape parts. In addition, injection molding is suitable for mass production and shaping complex products, and for other molding processing fields. In the field of injection molding, our expertise determines that we can offer our customers a wide selection of molds: single and multi-cavity molds, embedded-part injection molds, two-color injection molds, thin-wall molds, automatic threading molds, HASCO and DME standard molds, molds of various sizes, and molds weighing up to 10 tons. In HingTung, no matter the test mold or the mass production mold, each mold is executed in accordance with strict standard procedures to ensure the quality of mold design and manufacturing.

Implement the Highest Injection Processing Standards

The process of injection molding is a complex process that involves mold design, mold manufacturing, raw material characteristics and raw material pre-treatment methods, molding process, injection molding machine operation and other factors, and is closely related to the processing environmental conditions, product cooling time, post-processing technology. Moreover, the quality of the product also depends on the injection precision of the injection molding machine, measurement accuracy, as well as plasticizing pressure, injection pressure, holding pressure, pressure holding time, mold temperature, nozzle temperature, cooling system and other aspects of the influence. Hence, HingTung has been performing injection molding engineer training and quality control to the highest standards, with the purpose to make the product processing zero error, to provide customers with the highest quality and the best surface treatment of products, in the mean time, to ensure the product details and dimensions are fully in line with the customer drawings and meet the accuracy requirements.

The Injection Molding Process
First, the part is designed in detail including precise dimensions and other structural specifications. Prototypes are then made to provide a more tangible sample of the part. The goal here is to examine the structure and test it for stability, functionality, and aesthetics. If there are any errors or modifications to be made to the design, the prototype would be reconfigured and printed for a second evaluation. This is done until the design is perfected.

Once the part design is complete and approved, mold-making which is also known as tooling can begin. A mold is a structure made of steel or aluminum. It has two parts: a core and a cavity; the core is solid but the cavity is hollow. Both are designed to match every detail of the part design. Their dimensions, curves/corners, rifts, or ridges are all made in likeness to the part that is to be manufactured. It takes high precision to make the perfect mold design and the process can take several tries.
