![]() JLS Precision offers standard pilot punches and customized pilot punches. Our special pilot punches improve productivity and reduce manufacturing costs. Pilot punches are required to be manufactured in high precision, so they are usually made from hard metals, such as high-speed steels, tungsten carbide or other carbides. JLS offers a wide range of in-stock materials including tungsten carbide and high-speed steels (WF20, WF30, KG7, YG20, M2, SKD11, SKD51, SKD11, etc) Pilot Punches are usually used in progressive dies as a locating tool. When a punch pierces a hole in one station, the press cycles the die, and the material is moved to the next station. The pilot punch enters the hole and positions the material in an exacting location before the press cycles the next stroke. Pilot punches are ideal for tool designers that desire close tolerance, long-lasting, accurate pilots in high production, and high-strength materials. These pilots may also use for extrusion applications. JLS Precision Mold Parts Co., Ltd has been devoted to producing precision carbide components for more than 20 years. Our product scope covers precision carbide punch, bushes, pilot punch, ejector pin, pierce punch, motor connector stamping mold, etc. JLS devoted our full energies to standard and non-standard carbide mold components according to customers’ CAD drawings. For standards, we can manufacture according to Misumi, Punch, Din, ISO, and other standards. For non-standard parts, kindly send us your drawing with detailed requirement, we are glad to assist. #pilotpunch #ejectorpins #precisioncarbidepunch

JLS carbide punches will increase productivity by reducing downtime and replacement tooling costs. Punches manufactured in carbide can improve the quality of your products and extend the life of your tooling. JLS is a partner with you, supplying you with carbide components for your Die Set Assembly. The main components for die toolsets are: Die block – This is the main part that all the other parts are attached to. Punch plate – This part holds and supports the different punches in place. Blank punch – This part along with the blank die produces the blanked part. Pierce punch – This part along with the pierce die removes parts from the blanked finished part. Stripper plate – This is used to hold the material down on the blank/pierce die and strip the material of the punches. Pilot – This will help to place the sheet accurately for the next stage of operation. Guide, back gauge, or finger stop – These parts are all used to make sure that the material being worked on always goes in the same position, within the die, as the last one. Setting (stop) block – This part is used to control the depth that the punch goes into the die. Blanking dies – See blanking punch Pierce die – See pierce punch. Shank – used to hold in the presses. it should be aligned and situated at the center of gravity of the plate.

Correct punch and die clearance are crucial during the punching operation. Proper clearance produces a hole with approximately the top one third measuring the size of the punch and the bottom two-thirds flaring to the approximate inside diameter of the die. Insufficient clearance will usually result in a secondary shear on the material, producing additional wear on the punch. On the other hand, excessive clearance may produce a large flare as well as a burr on the bottom side of the material. Material “roll-over” may also happen along the top edge of the hole and may result in the punch’s sharp edge to break down quickly. There is no exact science for determining the proper clearance between the punch and the die. What may work for one particular type of material may be different for another. Follow the clearance chart below for the best results when punching mild steel. Punching Features It is the cheapest process of making holes in the strip or sheet metal for average to high fabrication. It is a quick process. It is able to create multiple shaped holes. Carbide Punch and dies are usually fabricated from conventional tool steel or carbides. It creates a burnished region roll-over, and die break on the sidewall of the resulting hole. |
