STEP BY STEP FOR MOULDING DESIGN

STEP BY STEP FOR MOULDING DESIGN
1. Detailed drawings and complete product that we will create. Consider the depreciation of the material that we will create products to enlarge the product image size (scale). The amount of shrinkage of each material vary depending on its type. (See catalog material).
2. Determine linenya partings, to determine the separation cavity and fixnya move. Try pemotongannya easy, flat and simple. Picture detail insert cavity and movenya fix by providing sufficient space from the edge of the product and place pengikatnya bolts. Determine also the thickness by providing a safe space (20-25 mm).
3. Determine where the ejector and ejectornya size. Imagine how the expenditure of cavitynya workpiece. When you have a sample we can imitate the place and size ejectornya. Try to place ejectornya symmetrical workpieces can be balanced so that when the process of issuance of the cavity. Try ejectornya size adapted to the existing catalog.
4. Determine the location and size of ejector returnya. Ejector return function to restore the position to place the original sets of ejector plate when closed molding. The size is adjusted with the specifications existing catalog. Try position symmetrical / balanced.
5. Images and determine the size of ejector plate and ejector plate stopper. Platnya adjust the thickness of the head of the ejector with the specification that we use. Give enough space to place screws pengencangnya.
6. Images and determine the size of cavity holder platenya move. Give enough space to place a guide pin and to have systems coolling. Preview and adjust the bolt position with the cavity pengencangnya move.
7. Determine and images that will guide pins we wear. Try to use standard parts. Design and size of the saw in a catalog.
8. Determine the vertical plate and the image, adjust the bolt position with the cavity pengencangnya plate holder.
9. Determine and images platenya clamping. Adjust bolts pengencangnya with vertical part of the plate. Consider the thickness of this plate to facilitate clampingnya on a machine.
10. Continue with the assy fix, image detail is paired with a fix Cavity Cavity move. Decide also where pengencangnya bolts.
11. Images and specify Cavity holder fix, make sure the position of bolts in accordance with the position fix bolt cavity. If necessary, please pin as a reference. Preview Guide bush with the appropriate position with the position of guide pin holder mounted on the cavity move. Give hole for the runner. Runner size commensurate with the existing standard parts in this catalog. Give space to coolling system.
12. Fig detail runner and locator ring that serves to mencenterkan hole with runners on molding nozzle holes exist in the plastic injection machine.
13. Check all parts drawings, make sure all bolt holes line and make sure the reference to the process of machining from a single reference.

Type of Plastic Material
There are two types of plastic materials as we know, namely:
1. Thermosetting material, which will experience a chemical change anything when heated, and will also be changing its form. Example: epoxy, silicon, resin, ... etc.
2. Thermoplastics, materials that will soften when heated and harden when cooled, without undergoing chemical changes. Example: PS, PP, PE, PA, ABS, ... etc.

Plastic molding is the process of forming workpiece / product with the basic ingredients of compound (plastic / mix) using tools such as mold or mold, whose implementation using heat treatment and delivery pressure.
