Shoe mold, usually refers to mould of sports shoes, sandals, slippers, and rubber shoes. Sport shoes is the main among all. Mold made from some processes like injection, extrusion, blow, casting, forging, smelting, stamping, and other methods to get the request mold and tool. It needs different design of mold because of different material. RB, EVA, TPR, etc. are popular material for various application. General speaking, shoe mold belongs to injection mold. There are some exceptions, such as CMEVA, which is combined injection and cold press. And some others are made of blow molding.

Silicon Carbide now is often used as non-oxide ceramic materials. Because it has better hardness, heat resistance, oxidation resistance, corrosion resistance and thermal conductivity than general ceramic materials. Hence it is widely used in structure of mechanical engineering and seal part of chemical engineering, even in extreme tough surroundings like under strong acid, alkali, high abrasion, high temperature and aerospace.
SiC is also known as corundum or silicon-refractory sand. ..Si is produced by smelting with quartz sand, petroleum coke (or coal), wood (green SiC production needs to add salt) and other raw materials at high temperature. Si is mainly divided into black SiC and green SiC, which both are hexagonal, specific gravity 3.20 ~ 3.25, micro hardness 2840 ~ 3320kg/mm2 .. Silicon is often used as non-oxide ceramics materials. Silicon carbide contains some impurities, including silica, silicon, carbon, iron, silicon and aluminum. The commercial benefits of Si are high melting point, hardness, and its Chemistry inertia.
Applied in grinding ceramic powder and other materials.

一般粗銑刀減少了切削變形，由原來的寬帶切屑分割成數條較窄的切屑，使得銑削過程中切屑的形 成捲曲和排屑情況得以改善，隨之降低了切削抗力，粗銑刀之外周刃為波浪形，由於切屑很細就會斷裂 ，切削抵抗會很小，加工面會呈凹凸不平狀，因此可從事進給大之重切削(粗加工)。

---

但由於切削振動很大，刀具和機器之接合部很容易變成很粗糙(摩擦腐蝕) ，因此應避免使用於高精 度之機器。特別是乾切削的時候，由於刀具很容易具有高熱，因此應將切削速度降低10至20％左右，以增長刀具壽命。

高效的切削技術和刀具已成為汽車製造業的基礎工藝和關鍵技術。高速切削、幹切削、硬切削等新的切削工藝正在改變傳統的加工工藝，顯現出強大的影響力。汽車工業是專用刀具應用繁多的行業，目前汽車製造業的機械加工所使用的刀具主要是超硬刀具材料，汽車工業一般常見加工如下:



加工工件
加工刀具
加工方式及速度


加工高強度鑄鐵件
CBN、SiN陶瓷、Ti基陶瓷及TiCN塗層刀具
銑削速度可達2200m/min


加工高矽(Si)鑄鋁件
PCD、超細硬質合金刀具
銑削速度可達到2200m/min，
鑽、鉸削速度分別可達80m/min和24m/min


加工精鍛結構鋼件
SiN陶瓷、Ti基陶瓷及TiCN塗層刀具
車削速度達200m/min


加工各種精鍛鋼製齒輪(內、外表面加工)
塗複TiCN鍍層的高鈷(Co)粉末冶金高速鋼材質的整體滾刀、剃齒刀及各類拉刀
滾削速度為 110m/min
剃齒切削速度為170m/min
拉削速度為10～25m/min。

燒結碳化物(碳化鎢、鎢鋼)有兩等級
一為純碳化物類及抗陷穴類。純碳化物只包含碳化物和鈷，強度及耐磨特性最好，任何其他物質加入均將減少其強度及耐磨性，通常用來切削鑄鐵及非鐵金屬材料。但純碳化物不耐高溫，在高熱下鋼屑易沾黏在刀面上，使刀面因擴散作用形成凹陷。而加入碳化鉭及碳化鈦之碳化物，因這兩成分熔點高於碳化鎢，故抗高溫性也相對提高，相對的強度及耐磨特性較純碳化物低。

Product：PCD Insert
Specification：Custom made according to your request.
Characteristics：There are hundreds of cutters designed for alloy wheels. Various cutters specialized for different type of wheels are well-designed. Regarding the pin hole problem of c asting which happens in diameter under 1mm, it may be improved by using PCD cutters. We can make special size (custom made) PCD inserts according to changeable types of wheels.PCD is kind of polycrystal material made by carborundum powder with solvent under high temperature and pressure. The hardness (around HV6000) is lower than natural carborundum. Comparing PCD cutter with carbide cutter, its hardness is triple – quadruple higher; wear resistance and tool life is 50 -100 times higher; promoting cutting speed 5 -20 times; roughness may reach Ra0.05μm. PCD cutter brings high cutting efficiency and stable accuracy.

工件受刀具之切削後，內部產生了塑性變形，其塑性流動程度之大小直接影響了切屑的形態。一般切屑的基本形態有：不連續切屑、連續切屑和積屑刀口的連續切屑等3種。

This type of CBN cutter is specialized for grinding glass parts. The controller should have pecking function to avoid bad chip removal, which is related to CBN particles since the particle size is in proportion to the roughness of surface. We should say 「grinding glass」 instead of 「cutting glass.」The spindle deflection will influence the grinding accuracy. Grinding is based on the consideration of smoothness, flatness, and parallelism. Press the surface of glass slowly and grind it by using abrasive. It is hard to control the smoothness, flatness, and parallelism under speedy cutting.

刀具材料性能的優劣是影響加工表面品質 、切削加工效率、刀具壽命的基本因素 。切削加工時，直接擔負切削工作的是刀具的切削部分。刀具切削性能的好壞大 多取決於構成刀具切削部分的材料、切削部分的幾何參數 及刀具結構的選擇和設計是否合理。切削加工生產率和刀具耐用度的高低、刀具消耗和加工成本的多少、加工精度和 表面品質的優劣等等，在很大程度上都取決於刀具材料的合理選擇。

The width of tip bottom is 0.10~0.25mmmm. The surface of work piece is very exquisite, no blunt and any cutting trace, no acrylic remnants left in the flute gap, and the design of central point is very special.
Usually the surface of work piece will become blush after cutting, but our tool with superior design won't have such problems. Hence, tool for wood cutting or for acrylic cutting should have different design. BW's cutter is much better than those imported products.
