What is a C frame press?


The C frame press (also commonly known as the gap frame press) is characterized by its unique frame style, resulting in a "C" shape around the backing plate. We offer C frame presses in a wide range of bed sizes and tonnage. 

Although side access to the forming area is required in many applications, C frame presses are usually best suited for applications requiring smaller bed sizes and lower tonnage, such as assembly. 

1. Application of C frame press 

In addition to stamping, manufacturers may perform other metal forming processes, such as: 
I Assembly: Two or more parts are held together by a C frame press. 
I Bending: Use C frame press to stretch a material, usually a plate or strip of metal, by moving around a straight axis and applying stress. After removing the applied stress, the bending will be permanently set. 
I Blanking: cutting out a piece of metal and leaving it in place. The rest of the material is discarded as scrap.  
I Coining: Highly compressed all surfaces of the workpiece in a closed die system.  
I Compaction: An object created by compressing a powder material, usually with a custom hydraulic compactor. 
I Crimping: An assembly technique in which a custom assembly press and appropriate tools are used to fold and flatten the material so that two pieces are firmly held together by pinching action.This technique is commonly used to connect sheet metal parts. 
I Deep drawing: The drawing of metal through a tapered die and then use C frame press to stretch it into a thinner shape. 
I Embossing: The process of using a C frame press to create an embossing design on a sheet from a male and female die, with no theoretical change in metal thickness. 
I Forming: Convert a flat metal workpiece into a 3-D part. 
I Piercing: Use a hydraulic C frame press to cut or press openings, such as sheets, boards, or holes in various parts.  
I Press fitting: pressing fit assembly parts.  
I Staking: A method of using a custom assembly press to hold two parts together permanently by pressing one part into another and causing the part to flow plastically at the joint.
I Straightening: Bend, twist, or stretch to correct any deviation in a rod, tube, or similar long part or shape relating to straightness. 
 I Trimming: A second cut or shearing operation, usually of a previously formed, stretched, or forged part. The goal is to "trim" away excess metal from the edges to give the part the desired shape and size. 

The most common C frame press applications include assembly, stamping and finishing.

Some industries that commonly rely on C frame press hydraulic presses include aerospace manufacturing, home appliances, automotive manufacturing ceramics, food and beverage processing, industrial, marine, medical, military and defense, packaging, and pulp and paper.

2. Advantages of C frame press

Besides those applications, there are some unique advantages of the C frame press.
I Three entrances into the working area facilitate the loading and unloading of parts and easy maintenance and adjustment of molds .
I More economical than flat press.
1 Machines with larger tonnage or bed sizes may use other materials to reinforce the frame to resist flexing or "yawning"We manufacture and supply the C frame press for many years. 
We also supply other kinds of press machines such as servo press and linkpress. Please contact us for more information and quote.
