Plastic injectio mold

Our team with good trained engineers who are capable of creating complex to simple designs and assemblies in 2D and 3D formats.

¿2D Part Drawings (.DWG, .DXF, .PDF etc.)
¿3D Modeling (.STEP, .STL, .IGES, .X_T etc.)
¿Auto Cad®
¿UG® NX8.5


Process Simulation

In DEX, we emphasize on the benefits of DFM to our clients with the knowledge that is powerful diagnostic tool will create a more efficient production cycle and ultimately increase profitability.

We are capable of addressing design issues at the earliest possible stage by utilizing Moldflow® simulation software to identify vital information that helps avoid costly part redesign, tooling changes or modifications such as:

¿Filling Pattern
¿Sink Mark Estimate
¿Warpage Trends
¿Time & Pressures


Plastic injectio mold



Our service runs from the initial design concept through to creating visuals, 3D CAD, prototyping, development and finally the production supply of moulded parts or assemblies. We utilise high-end 3D CAD (computer aided design) packages and can accept data from all the major design platforms such as Catia, Solidworks, Autocad, ProE and Unigraphics. We are also licensed users of VISI Flow software for the analysis of polymer flow properties, a must have for superior design and manufacture.

Over all the project phases from the very initial design concepts going through the prototype making, product validation with testing, mould and tooling making, assembly lines, first production trials and final product homologation.


Project Management¿

 Project Management

Detailed project managing procedure as follows:

<1> Firstly a series of engineering analysis will be carried out to your part drawing, including part &. mould structure analysis and Moldflow analysis etc.. Through analysis we can find the disfigurement on part design, and propose improvement, or send modified drawing for your reference and confirmation.


<2> We start 2D mould layout design. Normally it will takes 3~7 days to complete, and we will have one day to have an inner design checking and improving before sending the mould layout to you.
<3> We start to modify the mould layout after received you reply, till approval on the final design.
<4> Engineer dept. give a BOM, Puchase dept. prepare to ordering steel, mould base etc. and start full 3D mould design once receipt of  your confirmation letter on our mould design.
<5> Normally it takes 3~7 days to complete the 3D mould design. we will send the 3D file to you after design finished, for you review.
<6> When complete 3D mould design, CNC programming will be followed immediately, and all the 3D parts drawings will be transformed to 2D drawings with full mark of dimensions. Our tooling staff will carry on machining according to 2D component drawings.
<7> Project engineer will send you a timing schedule of the machining processing after your approval on our mould design, and from then a weekly report with mould pictures will be sent every Monday.
<8> We will record the molding condition of T1(the first trial), take pictures and short video of the process. After T1, we will arrange express send samples to you, with inspection report will be provided.
<9> After T1, mould engineer will going on the first mould checking according to the approved mould drawing. At the same time, we will improve the mould according to our inner review and any feedback from you. Latest samples and inspection report out of T2 will be sent to you for approval.
<10> If any specific surface finish is required, upon your approval on the sample, we will arrange to carry out mirror polishing or texture. Afterwards, new samples will be sent to you for viewing and approval.
<11> Upon receiving your final confirmation on the sample, ¿ if the mould is going to stay in our workshop for further production, we will preserve it and wait for your production order. ¿ if the mould is going to be exported, we will have final mould checking according to the mould drawing. The mould will be running 4~6 hours without stop after final mould checking, in order to make sure a successful running for future production. 
<12> To save your time to cleaning the mould after it arrives at your side, we apply W40 colorless antirust oil on the mould surface, and the mould will be vacuum-packed for transportation.
<13> Following documentation will be provided together with mould shipment.
