Abstract

The invention provides a one-time forming manufacture method of a stainless steel zipper. The method is characterized in comprising the following steps of 1, designing dies of parts of a stainless steel zipper body; 2, choosing metal powder for metal injection forming of the stainless steel zipper; 3, choosing a bonder for the metal injection forming of the stainless steel zipper; 4, mixing the metal powder and the bonding agent prepared in the process 2 and the process 3 into a uniform feeding material according to a preset volume or weight ratio; 5, injecting the uniform feeding material prepared in the process 4 to dies to be heated at high temperature and forming by cooling after flowing; 6, cooling and forming by adopting a wax-based bonder or a plastic bonder; 7, sintering the degrease stainless steel zipper to form a finished product. According to the method, defects caused by manufacturing a puller adopting a pressure casting method or a pressing method are well overcome, so that carving with complicated shapes and three-dimensional forming features is realized, waste is reduced, product performance is improved, the surface is fine, blisters are not easy to generate, oxidization does not easily occur, and subsequent processing and auxiliary equipment are not needed.

Description

A kind of stainless steel zipper one-time forming manufacturing method
Technical field
The present invention relates to a kind of stainless steel zipper of manufacturing, relate in particular to a kind of stainless steel zipper one-time forming manufacturing method, belong to metal injection molded stainless steel zipper and the manufacturing technology field thereof of utilizing.
Background technology
Current, pull head is produced and is conventionally adopted die casting and compact technique.Its technique is simply backward, has pollution in manufacturing process.Technology content compared with low, product percent defective is high, burr is many, low precision, be easily imitated, homogeneity dog-eat-dog, added value is low, labour intensive; Aspect use metal material, there is significant limitation simultaneously, can not realize anyization, only aspect the alloys such as iron, copper, aluminium, zinc, nickel, utilizing to some extent, can not aspect your material such as stainless steel, tool steel, high-density alloy, carbide alloy, titanium alloy, tungsten alloy, nickel based super alloy, intermetallic compound, aluminium oxide, zirconia, have breakthrough; In manufacturing process, can only level or vertical two-dimentional moulding up and down, be difficult to obtain pull head (containing draw ring, the pulling-on piece) body of complicated shape and three-dimensionally shaped feature.After die cast, rough surface, easy to foaming, oxidizable, moulding mark is obvious, needs following process and auxiliary equipment.Still there is at present the problems such as small scale, brand recognition is low, product specification is low, and technology competition is indifferent at China's zipper industry.Its main cause is exactly that the zipper product of most domestic enterprise concentrates on low-end market, and between enterprise, product homogeneity is serious, product development innovation ability deficiency, and product profit rate declines year by year, lacks international competitiveness.
Summary of the invention
The object of the invention is to overcome above weak point a kind of stainless steel zipper one-time forming manufacturing method is provided, this stainless steel zipper manufactured by metal injection molding utilizes a kind of Novel powder metallurgy near-net-shape technology of extending out from injection molding of plastics industry to manufacture slide fastener, overcome preferably and adopted die casting and drawing method to manufacture the defect that pull head brings, thereby reach the engraving of complicated shape and three-dimensionally shaped feature, cut the waste, enhance product performance.
The object of the invention is to reach like this, developed stainless steel zipper one-time forming manufacturing method, it is characterized in that: comprise following steps:.
1., the each part mold of design stainless steel zipper main body;
2., select metal injection molded stainless steel zipper metal dust;
3., select to be equipped with metal injection molded stainless steel zipper binding agent;
4., by 2. with metal dust that 3. prepared by process and binding agent in determined volume integral strength ratio mixing become even feeding;
5., the even feeding that 4. prepared by process is expelled to the mobile rear cooling forming of mold for heating at high temperature;
6., select wax-based binder or mould based binder cooling forming;
7., the above-mentioned degreasing stainless steel zipper of sintering forms finished product.
Described metal dust is that 304L powder of stainless steel or its size of 317L powder of stainless steel are 0.2≤40 μ m, and volume fraction is 30%-65%.
Described binding agent is chosen the one in thermoplastic systems binding agent or gelinite tying agent or thermosets tying agent or the knot agent of water-soluble system or the agent of inorganic matter knot, and its volume fraction is 20%-70%, and temperature range is at 80-150 degree.。
Described a kind of stainless steel zipper one-time forming manufacturing method is made into slide fastener.
Beneficial effect of the present invention, has overcome preferably and has adopted die casting and drawing method to manufacture the defect that pull head brings, thereby reached the engraving of complicated shape and three-dimensionally shaped feature, cut the waste, enhance product performance, surface fine, not easy to foaming, not oxidizable, without following process and auxiliary equipment.
The specific embodiment
Stainless steel zipper one-time forming manufacturing method, is characterized in that: comprise following steps:.
8., the each part mold of design stainless steel zipper main body;
9., select metal injection molded stainless steel zipper metal dust;
10., select to be equipped with metal injection molded stainless steel zipper binding agent;
by 2. with metal dust that 3. prepared by process and binding agent in determined volume integral strength ratio mixing become even feeding;
4. the even feeding that prepared by process is expelled to the mobile rear cooling forming of mold for heating at high temperature;
select wax-based binder or mould based binder cooling forming;
the above-mentioned degreasing stainless steel zipper of sintering forms finished product.
Described metal dust is that 304L powder of stainless steel or its size of 317L powder of stainless steel are 0.2≤40 μ m, and volume fraction is 30%-65%.
Described binding agent is chosen the one in thermoplastic systems binding agent or gelinite tying agent or thermosets tying agent or the knot agent of water-soluble system or the agent of inorganic matter knot, and its volume fraction is 20%-70%, and temperature range is at 80-150 degree.。
Described a kind of stainless steel zipper one-time forming manufacturing method is made into slide fastener.
