What Is Precision Molding?
It’s all about how you build the tool to build the part.’ ~ Alan Lipman, CEO Romar
Precision molding is the process of molding either silicone or plastic in a particular way, with a very high degree of accuracy and tolerance, to ensure repeatability in long machine runs.
As specialists in precision molding, we are able to mould these materials to achieve the required result, using the most cost effective methods.
With over 50 years experience in building precision moulds, we have the technical, engineering and creative expertise required to meet every precise standard. Romar is acknowledged and applauded worldwide for producing injection molded components of the very highest quality and precision.
Our experience in molding has seen products ranging from precision miniature components with micron dimensions to large components weighing in excess of 16kg.
If you're ready to collaborate with a team that understands the precise requirements of precision moulding and micromoulding, let Romar provide you with an innovative, end-to-end design and manufacturing solution. Contact Romar today.
What is metal casting?
Metal casting is the process of making objects by pouring molten metal into an empty shaped space. The metal then cools and hardens into the form given to it by this shaped mold. Casting is often a less expensive way to manufacture a piece compared with machining the part out of a piece of solid metal. There are many metal casting methods to choose from. What type of casting is most efficient depends on the metals used, the size of the run, and the complexity of the casting.
Before starting a production run, it is helpful to know some of the terms and methods from the foundry floor.
A mold is a cavity in a material that receives liquid metal and produces a cooled object in the shape of that cavity. Molds can be simple. The forms used to create ingots of metal are like loaf pans, with the metal simply poured inside and left to cool. Most molds are for more complex shapes and are based on a pattern. The pattern imprinted into a split mold. Half of the pattern is imprinted on one side of the mold and half on the other, and then the halves are clamped together before the mold is filled. By making the mold in two parts, the pattern can be withdrawn before filling. These molds can be made with a horizontal split
Cope and drag
In horizontal molding, the top half of the mold is called the cope, and the bottom half is called the drag.
Swing and ram
In vertical molding, the leading half of the mold is called the swing, and the back half is called the ram.
