Mould for Plastic Injection Sofa Chair with Comfortable Sitting

Product Description

Product Drawing

The first option is that Client provide us product sample, we are able to do sample 3D scan for the original sample, meanwhile we help client improve product design as per client idea and opinion. The second option is that client provide us detail 3D product drawing, we will check the details, analysis the part design and its plastic raw material. For some complicated parts, we may need to make the DFM report to show the client the detail problems on the part designs.The DFM report sent to client with PDF file or PPT file, from the report, client can get know the detail problems on the part design, and also would know the conception of the mould design. After presented the DFM report to client, client will discuss and tell us if they will need us to make the improvement for the part designs. Most of client will require us to change the part designs for them. As we know better on how to design the parts to fit for making moulds. In this way, we can save lots of time, because parts designs modified by us is faster.

Mould 3D/2D Drawing

Once the parts 3D designs confirmed, we start the mould 3D design. Before the mould 3D design, we need to know the detail plastic raw material shrinkage rate, injection machine detail specification and the detail requirement on the moulds standard parts those basic information.

Our mould designers are quite knowledgeable with 10+ years experiences,they are qualified to figue out completed and excellent mold design with detailed ejector system,cooling system and runner system.mould main structure already come into mind, only if there are some small details need to discuss with client and make change on the mould 3D design. Such as limit switch, shot counter, which we didn't make them in the first time submited moulds design.

 Injection Mould CNC Machining

Once moulds design confirmed by client, we can go on the mould steel purchasing and cutting. Steel plates are cut by steel supplier. We just send the steel purchase order to the supplier. The steel detail sizes and detail tooling request already marked on the purchase order sheet. Steel cutting is the first step of the mould tooling. Steel cutting job were done by steel supplier factory. Before the steel plates delivered to our factory, we will check the steel hardness. Inspect the steel hardness can check the steel quality. As every different steel have their own hardness level. If hardness can match the steel which ordered, means that steel is exact what you order. For commodity mould, the main rough tooling machine is CNC milling tooling. But for some big parts mould, use tooling centre to tool the mould. As that machine tool big mould, much faster. After rough tooling,moulds will be going on with precise tooling, including CNC high speed milling tooling and CNC engraving tooling.

Precise tooling include CNC engraving tooling, high speed cnc milling tooling, EDM tooling, EDW tooling, etc.
CNC engraving tooling include high speed, middle speed and normal speed. The tooling precision high speed > middle speed > normal speed. So when parts require high precise, means tooling require high speed cnc engraving tooling. At the same time, the tooling cost high speed > middle speed > normal speed. So parts sizes tolerance request higher, the tooling cost higher. Some sizes, like ribs, sizes are very small and narrow, can not be directly tooled by cnc engraving tooling. In this situation, we need to make electrode and tool the mold by EDM. Mainly electrode material include carbon and copper. Copper electrode cost is higher than carbon electrode. The advantage for copper electrode is that its life longer and not easy broken. So some very very small sizes EDM tooling will use copper electrode.

EDW tooling also used to tool small sizes, but which is 0° angle with straight direction. EDW tooling include slow speed and high speed. 

Normally cooling lines and ejector pins holes are tooled by deep hole drilling tooling. As normal drilling machine tooling, holes may not straight. Therefor, especially for ejector pins holes, not allowed to be tooled by normal drilling machine.

After precise tooling finish and cooling lines and ejector pins holes ready tooled, moulds can be assembled and polished. Some home appliances mould need high shinning finish on the part surface, mould polish request is very high. Therefore this mould can't be polished by polishing machine, they need to be polished by manual. After that we take mould testing and provide client good performance trial samples for approval. Our testing machines are Haitian injection machines from small tonnage to large tonnage, including  MA 160Ton, MA 250 Ton, MA 320 Ton, MA 470Ton, MA530 Ton, MA 800Ton, MA1000Ton.

Testing plastic raw material can be norminated brand and model number by client. Mould trial videoes and injection molding prameters will be provided to client by us.
