3. Sino Pipe Fitting Mould Co. is the professional and high classic pipe fitting mould manufacturers in the world. To consider the big moulds investment of our customers, we are innovating on the mould structures in order to reduce pipe fitting moulds cost and improve the moulds quality, SINO-PF's R&D department are researching on different type's pipe fitting mould's structures, components standard, machining process, quality controlling...Annually, SINO-PF produce more than 1000 sets of pipe fitting moulds, most of them are delivered to Spain, German, France, Italy, Portugal, Argentina, Chile, Brazil, Mexico Russia,Israel, Saudi Arabia, Iran, Egypt, Tunisia, South Africa. SINO-PF almost has all kinds of moulds design which are ready made, have herself's mould design standard. Based on the outstanding mould design, SINO-PF has strong machining capacity and very professional tooling process, around 150 assembling workshop member have very high assembling and mould injection testing inspection capacity. We keen on the high quality combine with low cost and on time delivery.

6. PVC pipe fitting Mould ( for high pressure and low pressure = for water supplying and water discharging) 1. CPVC pipe fitting mould for high pressure. 2. UPVC pipe fitting mould for water drainage 3. PVC belling pipe fitting mould( with collapsible cores for pressure water supply). 4. Electricity cable pipe fitting mould, built in-wall various PVC pipe fittings. The technical solutions for PVC pipe fitting molding and PVC pipe fitting mould manufacturing. PVC is a kind of special material which need special injection molding process. The basic feature of PVC material: 1. Hard PVC material low MFI 2. PVC with high corrosive 3. PVC with low temperature melting 4. Easy decomposition ……………. Because of above basic features, PVC material has special molding process. The injection molding machine need precise temperature controlling and the material can not be heated for a long time. We can say it is very sensitive with the temperature. Also for this reason, there is no PVC pipe fitting mould which can use hot runner system. Because PVC materials high corrosive, PVC pipe fitting mould must need the steel be high quality stainless steel, and also deep hardened to around HRC50. Since the low MFI, when you make the runner and injection gate of a PVC pipe fitting mould, we need special design. For the big volume PVC injection molding, some time we need a very big runner and injection gate. But the runner cant be recycled, what should we do? I think the only way is to reduce the runner flowing distance to reduce the runner waste.

7. PVC fitting molding size from 25mm up to 160mm diameter. PVC fitting type : Coupler, TEE, Reducer, Elbow, Cross, End cap, Socket PVC fitting mould cavity Nr.: from single cavity to 32 cavities PVC fitting mould. PVC fitting mould cavity and core steel: DIN 1. 2316 stainless made by Thyssen Krup German. tempered with HRC 48. Cooling: Optimal cooling effect, with mold-max adaption available. Stroke switch for slide action safety and prolong the CPVC fitting mould life.

14. PPR pipe fitting is specially for water supplying piping system, the connection of the fitting with the pipe has 3 different types. 1. gluing type. 2. welding type. 3. screwing type. Based on the function, we divided the PPR pipe fitting mould into below 4 different types. A. normal PPR pipe fitting mould B. Self welding PPR pipe fitting mould. C. PPR pipe fitting mould unscrewing ejection. D. PPR metal over molding pipe fitting mould The technical points for PPR pipe fitting moulds. 1. how to avoid the shrinkage marks on the fitting. 2. how to increasing the injection molding speed. 3. how to realize the cavities and cores interchangeable. 4. if there are metal bolt or nuts inesrts, how realized the automatic feeding of the metal parts. 5. the injection parameters' controlling, this is also very important, as because the thick wall of PPR pipe fitting, the pressure holding time, injection pressure and injection speed... all these effect the dimensions of the ID and OD.........

17. PP pipe fitting mould can be divided as below series: 1. PP belling pipe fitting mould 2. PP drainage pipe fitting mould 3. PPH belling pipe fitting mould 4. PPH sanitary wares mould By the mould industrial, we call belling pipe fitting mould series, but collapsible slide core pipe fitting mould. As because the collapsible slide core is a complex system. We need to make the slide core very precise and durable. There are many special technical points. a. Use which machining process to cut out the fix and moving parts of collapsible cores? b. Which steel and the hardness of the fix and moving parts of the collapsible cores? c. The cooling design on the fix and moving parts of the collapsible cores. Sino Pipe Fitting Mould has made so many standard collapsible cores in stock, the diameter ranges from Dia32mm to Dia160mm. In this way, we can improve our delivery time. From the normal 120 days, now we can deliver 50 sets of different moulds within 60 days.

18. PP or PPH belling pipe fitting molding size from 25mm up to 160mm diameter. PP or PPH belling pipe fitting type : Coupler, TEE, Reducer, Elbow, Cross, End cap, Socket PP or PPH belling pipe fitting mould cavity Nr.: from single cavity to 32 cavities PP or PPH belling pipe fitting mould. PP or PPH belling pipe fitting mould cavity and core steel: DIN 1. 2316 stainless made by Thyssen Krup German. tempered with HRC 48. Cooling: Optimal cooling effect, with mold-max adaption available. Stroke switch for slide action safety and prolong the PP or PPH belling pipe fitting mould life.
