Plastics Injection Mouldings General large parts

الوصف

The kinds are as below:injection mouldings, blow mouldings, rotational mouldings, fabricated acrylic, extrusions, pultrusions, vacuum formed, laser engraving, and so on…… The majority of what we do is injection moulded plastics - both the toolmaking and the moulding - and both of these are done in-house. Toolmaking Our toolmaking capacity is about *0 average sized tools per month. The tool room runs *4 hours per 6 or 7 days per week depending on our workload. The main tool steels we use are:  **8H is a Swedish (Assab) pre-hardened tool steel and is equivalent to AISI P*1. We mainly use it for PC and ABS parts.  NAK*0 is a Japanese (Daido) pre-hardened tool steel and is equivalent to AISI P*1. We mainly use it for PC and ABS parts.  M**0 is a German (Bohler) high chromium pre-hardened tool steel and is equivalent to AISI **0. We mainly use it for Acrylic parts that require a mirror finish.  S**6H is Swedish (Assab) pre-hardened stainless tool steel and is equivalent to AISI **0. We mainly use it for PVC parts. All of the tool steels are pre-hardened and have a minimum life of **0, **0 shots with minimal maintenance. With normal maintenance, the tools should have a life of at least 1, **0, **0 shots. We do NOT use soft steel, even if the moulding quantity is only low. The smallest job we have done is to mould **4 parts from a tool capable of making **0, **0 but that is all the customer wanted. Moulding The majority of the plastic we use is from well know companies such as GE and Dow from the USA and ChiMei from Taiwan. We use very little China made plastic because it is inconsistent from batch to batch. For the mouldings, we now have 6 injection machines as follows: Machine Size Max. Shot Weight (grams) Max. Tool Size (mm) 1 x **0 ton **8 **0x**0 1 x **0 ton **5 **0x**0 1 x**0 ton **4 **0x**0 2 x **0 ton **6 **0x**0 1 x **0 ton **0 **0x**0 The longest part we have do so far is half a tube **0mm long and *0mm diameter. The largest part we can currently mould in a rectangular shape, on the **0 ton machine, is about **0x**0mm, depending on the depth of the part. Multi-cavity tools identify each moulded part as 1, 2, 3, 4 etc via an ejector pin. Samples from tool trials are identified as A, B, C etc via an ejector pin.
