OUR SERVICES AND ADVANTAGES

Engineering & Design

moulddesign

We are adhering to the “Engineering on-site” industrial guideline. The engineering software Pro-E, SolidWorks, UG, AutoCAD, MoldFlow Mold Advisor help us to control the product and the mold structure in the engineering design phase.

Our experienced engineering team could design and create 3D mould models in .stp / .step / .x_t based on part models / hand sketches / physical samples provided by the customers.

Mold Flow Analysis

Mold Flow

Once the drawing is completed it will go through a MoldFlow analysis to insure the product can be injection molded with optimal manufacturability.

This step allows for any defects in the product design to be identified and resolved before a prototype is made.

Mould Fabrication

Even for a very complex part we got very good results from Why Mould. We did a lot of projects with Why Mould during the last 5 years and they always did an outstanding job – high quality (I can also recommend their painting logo service and assembling), reliable, extremely fast and perfect communication. I highly appreciate working with Cici and Julie and already recommended them to many of our partners.

 What is Mould Design

       Mould design is an important part of the development process when considering the production of a new molding.  Some considerations are given below,

The shape

The shape of the moulded part has a direct bearing on the time involved in making the mould, the cycle time of the molding. For example, undercuts and deep screw threads often require a separate moving part which increases the cycle time of each molding operation. Where moldings have significantly varying thickness, cooling has to be controlled very carefully otherwise depressions form (sink marks) on the outer surface of the molding caused by excessive shrinkage of the thick section of the molding.

The angles

•Angles on the side walls are necessary to ensure the molding can be removed from the mould.

The surface

The surface finish of the molding needs to be decided before the mould is completed. Embossing, etching and other finishes can be added to the moulding to enhance the aesthetic qualities of the molding. Any imperfection on the finish of the molding will transfer to every mould made.

The thickness

Weight, surface area and thickness of the molding directly affect cycle time. Where moldings have significantly varying thickness, cooling has to be controlled very carefully otherwise depressions form (sink marks) on the outer surface of the molding caused by excessive shrinkage of the thick section of the molding.

The number of cavities

The number of cavities in a mould is governed by the number of units per annum required. The number of cavities directly affects the size of machine required for the multi-cavity mould; this in turn affects the cost of the mould and the unit cost of the molding.

Where there are many cavities, each one must be uniform compared to the others and the cooling profile needs to ensure that the outer and inner cavities cool at an equal rate, otherwise moulds of differing dimension will result. Hot runner systems are usually used for multi-cavity systems. This reduces the cycle time and amount of waste material formed but increases the overall cost of moulds.

The insert

The need for an insert or label to be inserted during the molding sequence has to be considered at the mould design stage.

The injection point

All injection moulds require a point or points at which the molten plastic is introduced into them. If not considered at the design stage, this can leave unsightly surface blemishes on the finished molding which require a further stage to remove them, incurring extra costs.
