5 Major Steps of Plastic Product Development and Production

product development

With the continuous progress of society and the continuous changes in the market, people’s needs are constantly upgraded, and new product development can open up a larger market. After researching the market, the company makes a project decision on new products. Next, when you contact us, we will assist you through the development and manufacturing process of your new product, from design to realization, from prototyping to high-volume injection molding production.

For the realization of injection molding products, designers need to first understand the quality requirements of the products, and then design products that meet the realization of injection molding. From the beginning of product design, designers and engineers need to understand the quality requirements of product used to select the raw materials used, confirm whether there is a problem with product injection and filling according to the material properties, and then consider whether the mold can be filled and demolded to take out the product. Complete the design of injection molded products.

Rapid prototyping for product development

At present, there are three common processes for prototype production: 3D printing, CNC machining, and vacuum casting.

CNC machining for prototyping

CNC machining is currently the most widely used and can process product samples with relatively high precision. The main applied materials are ABS, PC, PMMA, PP, aluminum, copper, etc. Bakelite and aluminum alloys are commonly used in the production of fixtures and other products. Advantages of CNC prototype: good toughness, high tension, low cost, and wide selection of materials.

3D printing for prototyping

Prototype sample production is fast. Generally speaking, the speed of using SLA process to print prototypes is 3 times that of CNC production of prototypes, so 3D printing is the first choice for small parts and small batches of prototypes. The whole process of 3D printing prototype does not require human intervention, reducing the problem of prototype deformation. In addition, there are more optional materials for 3D printing prototypes.

Vacuum casting for prototyping

The product samples produced by vacuum molding have a certain percentage of shrinkage, and the cost of vacuum replicating product samples is generally lower than that of CNC machining.

After the design is verified by the rapid prototype, the parts that do not meet the design and manufacturing process need to be modified again until the design of the product meets the requirements of mass manufacturing.

Injection mold for product development

The injection mold and the processing of the mold are redesigned by the engineer. The injection mold is the first tool to realize the product. There are many problems to be considered in the mold design, including the selection of the glue feeding position, the choice of the glue feeding method, the flow analysis of the material in the cavity during filling, and the cooling control requirements. The realization of mold temperature, the standardization of mold installation, the sequence of mold actions to ensure product release and removal, the matching of technical parameters of injection molding and auxiliary equipment to meet scientific molding requirements, mold design life, mold maintenance, industry or customer standards matching, etc.

Product scientific molding trial production. Process trial production to obtain product samples. After the samples are approved, the stability of mass production is verified. Recording standard process: material injection physical property data collation, equipment technical parameter matching certification, mold assembly drawings and action description, product quality document reading and measurement preparation, mold installation and action confirmation, low-pressure protection validity and rationality confirmation, high pressure clamping pressure calculation, Test glue feed balance, test effective viscosity, record filling data, test pressure loss, test glue port closure, test melting temperature, measure and confirm product quality, confirm process range, confirm trial production repeatability, record process and data in detail.

Surface finishing for product development

Your parts and products also need surface treatment after machining to achieve a better appearance and higher product value. Whether metal or plastic, we offer a wide range of finishes to give your project the perfect finishing touch.

For metal fittings, the main surface treatments are: anodizing, electrochemical polishing, electroplating, sandblasting, shot blasting, polishing, rolling, polishing, brushing, spraying, painting, oiling, blue and black, phosphating, Pickling, electroless plating of various metals and alloys, TD treatment, QPQ treatment, chemical oxidation, etc.

The surface treatment processes for plastic products are mainly: spray paint, UV paint, water transfer, thermal transfer, anode, etching, electroplating, rubber paint, pearl powder, laser engraving, and chameleon.
