Precision Investment Casting/Lost Wax Casting
Max Prototype limited
Max Prototype is not just a dedicated prototype manufacturer; we are also a professional and well
organized high precision investment casting/Lost wax supplier in
We also provide a wide range of secondary processes to support investment casting parts. Welding, grinding, polishing, sandblasting, painting and physical vapor depositions (PVD) are available in house. Max prototype offers a one-stop shop provider for your final product.
Investment Casting Process Introduction
Max Prototype also apply 3D printed wax to make single investment casted stainless steel and titanium alloy parts which could help customer to verify both product design and supplier's whole manufacturing capability though prototype making.
Stainless Steel
Investment Casting
Titanium Alloy Investment Casting
Investment casting is suitable for products that need requirements as below, but not limited to:
Reasonable lower price: less expensive than full CNC machining but same quality.
Various Metal Material: most of tool steel, stainless steel, titanium alloy are available.
High physical property requirement: achieve 90% above of material physical properties.
Complex 3 dimensional shape: as complex shape as injection molded or die casted parts.
Low volume to high volume: single part possible, the higher volume, the more cost effective.
Why you should choose us!
Investment casting combined with secondart operation is sure a labor-intensive and management-intensive production process. Manufacturing cost and process variation are always big concerns generated by customer, which is reason that we introduces and implements TPS production ststem and PPAP quality assurance system in our whole production line.
Over 50 processes involved to produce a single final part.
Manual operations get involved in most of manufacturing processes.
Lot of process variation to produce quality uncertainty of final product
Investment casting with wax at middle temperature molten point, shell mold with silica sol and zirconium oxide sand technology is almost net molding process which directly achieves your design intention of final product. Compared to water glass technology, the silica sol method is always achieves much higher dimension tolerance and superior surface treatment and is an advanced and precision casting process.
1 All necessary inspection tools and test equipment are in place based on internal quality control procedure or follow customer requirement (CMM inspection machine, chemical composition test Equipment, metal graphic test machine , X-ray test machine, slurry related test tool kits, Tensile strength test machine, salt spray test machine and others)
2 Mold design and manufacture in house and documented mold design and mold inspection report
3 First article inspection and record (dimension, physical property and cosmetic), Inspection is based on investment casting inspection plan and casting parts linear tolerance guideline.
4 Production trial (PPAP procedure introduced, working instruction of each process and Investment Casting Process Control Plan of whole production process in place, Target sample and specific product quality criteria in place).Please take a look at one example of the whole information about the stainless steel product invesment casting process control plan.
5 Evaluation of Production trial (Process audited report, data collected from key process, process capability study, quality criteria revised)
6 Mass production (Routing process audit, sampling inspection for semi-part and final part). Inspection is also based on updated investment casting inspection plan and casting parts linear tolerance guideline.
7 Continue improvement procedure (corrective action plan) applied in any small specific quality issue and common quality issues in whole manufacturing process. The effectiveness of all corrective actions will be routine evaluated for further improvement, this procedure will repeat agin and agin untill specific issues resolved and passed the audit.
If you are starting a new plastic project that need injection molding process, even you do not have final 3D drawing or even you do not have enough experience to design a part that is suitable for injection mold. We can input valuable information to improve your design in a cost effective way. Once we receive drawing, our core team will review the design to check the draft angle, consistency of wall thickness, ejector pin location, parting line, injection gate location and any design issues. All what we do is to help identify any quality issues.
