Computer Numerical Control (CNC) machining is a process used in the manufacturing sector that involves the use of computers to control machine tools and it can be used to modify die cast part and produce features that can't be produced in the die casting mold, which allows us to customize our machining process to meet our customers specific requirements and budget.


A casting is not always the final product and some extra finishing steps may be necessary in order to achieve the right final result. The finishing process for casting is one of our specialties in which we acquire a lot of experience and expertise throughout the years. OnTops has in-house machining facility with 12 machining centers and 14 CNC lathes offering a wide range of capabilities. For a long time, OnTops was one of the few in Vietnam offering a combination of castings and CNC machining under one roof.

Different type of machining available: drilling; tapping; milling; boring; lathe and turning; and grinding.



Die casting is one of the most common alloys used for the metal thermal forming process. One of the main benefits of aluminum die-cast parts is that they have the advantages of good product quality, high production efficiency, and excellent economic effect. Aluminum die-casting parts are also chosen for their corrosion resistance and good mechanical properties making them the first choice for many applications from consumer electronic housing to automotive to industrial construction.

With over two decades of experience, we handle every aspect of production from the initial design and planning process to the finishing and delivery of your specialized parts. We take advantage of the precision and quality die casting offers while optimizing the results with engineering and quality control. Aluminum die-casting parts are easy to machine for high precision requirements and can be chromated, anodized, and powder coated without difficulty.

Our Aluminum die-casting facility consists of 14 die casting machines ranging from 125 Tons to 1200 Tons of maximum locking force.
