Products introduction

Mold Design
Why you need a china injection molding company to help you do design job?
Because we can providing our clients with professional solutions to industrial/mold design of new products. Let us help ensure your product can be manufactured. In past 10 years ,a lot of clients need such design service, customer will take some sample from exhibition or competitor side, we will copy and change style , structure from old sample or our clients only have a idea for product and they need turn their idea into really 3d model. During design process, we will change the parts more easy for molds tools making in future
It is really enhancing the value of products by the most economical investment and turning the solutions into the "Design keys" in practice.
Injection molded plastic parts can be designed to provide good looking products that consumers want to buy at no additional cost over boring products that have no sales appeal. To do this you need the right product concept, the right people, and the right tools. We have capacity to treat Solidworks, Pro/engineering, UGII ,Catia famous 3D software.
With our experience and expertise in 3D software technologies can help you in 3D Plastic product design. Our technology based services in product structure analysis, injection mould design and making ,injection molding to an extra edge to enhance our core plastic product design capabilities. We can assist you with plastic product designing from the conceptual stage, or if widespread modifications are required to go into the process, working closely with rotational molder we ensure a successful launch of your product.
Our Design team with high-calibre, teamwork spirit and innovation capacities. Our service is not only a concept for design but also consider really mould making in future
which will realize a material leap from initial ideas to final products.

Contact us now and you give get extra service not only simple plastic product design!

Design tips:

Sink mark
A Sink Mark can be defined as a depression, resembling a dimple or groove,
caused by excessive localized shrinking of the material after the part has cooled.

(FIG 1)

(FIG 2)how to reduce sink mark, design thickness consistent

However, there are several aspects of tooling design available to the toolmaker that can influence sink. Cooling-channel design, gate type, and gate size can have a wide variety of effects. For example, a small gate such as a tunnel gate freezes off much quicker than an edge gate. Premature gate freeze-off will reduce the available packing time in the cavity, which can increase the likelihood of sink marks.

(FIG 3)

Prevent Warping
Warp in injection molded parts is caused by uneven stress. There are only 4 primary plastic processing variables in the injection molding process – cavity pressure, melt temperature, fill rate, and cooling rate.
The general rule is change design Reduce thick and thin transition,also use ribs design instead of big thickness area.


Draft angle of injection molds design in china
Plastic parts design draft angle to prevent part sticking on the mold and ejector marks a small push caused by the molding process. In addition, you need to have done enough product surface with polish and draft angle. Do not forget the ribs should not exceed 60% of wall thickness
