ENGINERING

The part will be proceed to Moldflow analyse before the mold drawing are layouted.

CNC MACHINING


CNC Machines are taking care of the 90% manufacturing process, and also it’s the core processing of a mold quality, Such as cores,cavities, slides,lifters,mostly can be CNC rough/fine machined, we can judge a component good or bad visually by checking how smooth the faces especially the curve faces,abnormal shape,then go to next inspection step, normally the tolerance accuracy can reach to +/-0.01 mm.

WIRE CUT

Wire cutting is mainly to some of the high precision features,like some ribs,tiny holes features,as well as the angled face which is not able to achieve by grinding machine etc. accuracy can be +/-0.001,most of the ejector holes also can be wire cut which is much more better than drilling holes.

EDM MACHINING

EDM machining is to through high voltage short circuit melting the extra metal that CNC machine are not able to cut,typically to burn the Radius in between two ribs or some kind of corner that the cutter can not reach.

GRINDING

GRINDING is mainly to machine the flat features to drawing, typically for the square components which can be flat positioned, the accuracy can be +/-0.001. and the faces is really beautiful,like the wear plates,sliders,inserted pins,etc.

INSPECTION

INSPECTION PHRASE is extremely import part of all the machining, we perform components be check to drawing/data after every process, make sure it’s machined as per the drawing’s required dimension, otherwise it will be rejected and been rework.

D.After the cavity quantity is confirmed, next step will be start the layout design, That is, the arrangement of the cavity position, the arrangement of the cavity involves the mold size, the design of the pouring system, the balance of the pouring system, the design of the core pulling (sliding block) mechanism, the design of the insert and the core, the design of the heat exchange system, the above problems and the selection of the parting surface and gate location, so the specific design process, to make necessary adjustments, in order to achieve a more perfect design


PARTING LINE

A.Do not affect the appearance
B.IF It is helpful to ensure the accuracy of the product, mold processing, especially the processing of the cavity
C.IF It is conducive to the design of pouring system, exhaust system and cooling system
D.If it’s Conducive to the opening of the mold (parting, stripping) to ensure that in the opening of the mold, so that the product stay on the side of the moving mold

GATING DESIGN

1.The gating system design includes the selection of the main channel, the determination of the section shape and size of the split channel, the selection of the gate location, the gate form and the size of the gate section,When using the sub gate, in order to ensure the shedding of the diverter, attention should also be paid to the design of the gate device, the nine gate mechanism of the gate device.When designing the gating system, the first step is to select the location of the gate. The choice of gate location is directly related to the quality of product molding and the smooth process of injection
Gate location should be selected in accordance with the following principles
① Gate location should be selected on the parting surface as far as possible, so as to facilitate the cleaning of gate during mold processing and use
② The distance between the gate position and all parts of the cavity should be as consistent as possible, and the flow should be minimal
③ The location of the gate should ensure that when the plastic flows into the cavity, the wide, thick wall part of the cavity is smooth, so as to facilitate the smooth flow of plastic
④ The gate position should be opened in the plastic parts at the thickest section
⑤ Avoid plastic in the flow down the cavity wall, core or insert, so that the plastic can flow into the cavity as soon as possible, and avoid the core or insert deformation
⑥ Try to avoid making the product produce weld marks, or make the weld marks produce unimportant parts of the product
⑦ The location of the gate and the direction of plastic inflow should enable the plastic to flow evenly along the direction parallel to the cavity when it flows into the cavity, and facilitate the discharge of gas in the cavity
⑧ he gate should be set on the part of the product that is easiest to remove, while not affecting the appearance of the product as much as possible

VENTING DESIGN

The Venting system plays an important role in ensuring the quality of the product
① The VENTING groove is generally located in the part of the cavity that is finally filled. The depth of the exhaust groove varies with different plastics. Basically, the maximum clearance allowed by the plastic does not produce a flying edge is determined
② Use core insert,ejector pins clearance or special venting pins.


COOLING DESIGN

① The design of cooling system is a relatively complicated work, that is, to consider the cooling effect and the uniformity of cooling, but also to consider the impact of the cooling system on the overall structure of the mold
② The arrangement of cooling system and the specific form of cooling system
③ Determine the location and size of the cooling system
④ Key parts such as moving mold or insert cooling
⑤ Cooling of side sliders and side cores
⑥ Design of cooling element and selection of cooling standard element
