We are developing a range of chairs with plastic shells (used with a variety of bases) for an international furniture brand. I am interested to hear from reps and engineers with suggestions of innovative advanced polymers. This will be a high quality modern range that will sell into top commercial fit-outs.
Plastic Injection Mould company is a leader among mould makers. Our main focus is creating the highest quality products. Plastic Injection Mould company is a china injection mould company. Our company concentrates on mould design and mould manufacture. The main products are Plastic Injection Mould, Injection Moulding and Custom Plastic Moulds.
I suggest Compression moulding with sheet moulding compound (SMC). We supply seats to the Jetski industry where they neeed high strength, impact resistence, light weight, modulus and thin cross sections. Are SMC fiberglass have these properties :
Flex Strength > 85,000 psi
Flex Modulus > 3.0 x 10 to the 6 psi
Tensile Strength > 50,000 psi
Tensile Modulus > 3.8 x 10 to the 6 psi
Impact, notched > 33
Compression strength > 42,000 PSI
Moulding with harden steel match dies, good repeatability and fast cycle time. The SMC is also cost effective.
For an immediate solution to the problem I would try high flex homo and if not sufficient add fillers such as talc or glass fiber. While this would increase the price of the chair it will buy me time to perform a study of the mould and a DOA in order to solve the problem.
I entered the phenolic business in 1973, just a little before Union Carbide decided to exit the phenolic business. I spent 7 years with Valite Industrial Resins and 10 years with Durez, both phenolic manufacturers, doing technical service and compound development.
I agree, although the real chemistry is in plasric mould making the resin, there are still many challenges in setting up a compounding line. Back in the '70's there were a number of small companies that bought resin and just did the compounding, but I'm not sure you can do that for 30-40 MT per month. I had customers that used that much material in a week back then and they didn't want to set up a compounding line.
After people contribute answers, Reha discloses that he is already or about to manufacture 30 – 40 tonnes of cookware handles a month. It appears that he has a BSc and is the Production Manager at the factory and has 3 years experience there. I feel that asking the question was disingenuous. Any established factory with such a requirement would only have to contact companies, who sell phenolic moulding compounds and ask his question to have them knocking at his door with the help that he requires. If having done that, there remained issues, then I could understand the posting of questions.
