Mold making for export, apply to HASCO or DME
Our mold making room is fully equipped to manufacture custom plastic molds and machined steel parts in-house, 90% of our injection molds are exported to European and north America, we are familiar with HASCO and DME standard after many years' focus on export market. Averagely we can supply 25 sets of molds per month, lead time is around 25-35 days depends on the complexity of mold structure, mould bases supplies by LKM, mold steel and heat treatment with certificates apply to customers' specification, maximum machining capacity 7.5ton, minimum precision 0.005mm.
Our mould making capacities and experiences include:
- Shuttle and Insert Molds
- Expandable and Interchangeable molds
- Multiple Slide Action Molds
- Stripper and Floating Cavity Plate Molds
- Hot Runner System
- Unscrewing Molds
Mold steel we frequently used:
1.2344, 12343, S136, LKM2316, LKM738H, 1.2083, 1.2312, 1.1730, H13, P20, MOLDMAX-HH.
To lower down the cost and increase the efficiency for your companies, we pay special attention to injection mold making process control and manufacture correctness, as less as possible rework or mold trail out makes cost and lead-time as less as possible, we did it and are working on for better, in the past year, we had 97% positive feedback for the plastic injection molds we manufactured.
Mold making for molding in-house
You are welcome to inquiry us for custom plastic injection molding, it would be an advantage for you to have a China mold maker who are also capable of plastic injection mould making with reasonable prices. With our experiences and acknowledge of molds and injection molding, we are able to supply the best molding solution, it means high quality, most economical processing way, quick turn around. The plastic injection molds stay in our company for production would allow us to design and make in a much efficiency way, it means less time spend on technical applicable, unique accessories. So we can make moulds in a short notice, of course, at a much cheaper price. If you have any projects with small volume demands, it would be a wise choice to come to Aco Mold.
CNC machined parts, high precision and in short notice!
We also manufacture precision machined parts of plastic mold, die-casting mold, 0.01-0.02mm proposed to leave for final fitting in customer's own mold factory, we are able to do this in a short notice to meet your company's time table for their whole mold project, normally the delivery time we offered is 10-18 days or even less depends on the ordered quantities. Harden treatment steel would need a little longer time. Full measurement report is available, delivery by DHL, UPS, TNT or air shipping.
Excellence Mold maintenance
All of the plastic injection molds manufactured and stay at Aco Mold for injection molding is well organized to put on storage after molding production is finished temperately. Core and cavity would be covered by anti-rust spray, mold plate is clean without any mess, it would be labeled and identified to easy to accesses for next run. You can count on us no matter when you need more plastic parts. Any changes of the parts and molds will be recorded and traceable.
All of the injection molds for export are delivered with 2D/3D design drawings, NC programming data contained in a CD. EDM copper, interchangeable inserts, wearing parts. This would help your company to do maintenance at your facility very easy as well, such as modification on mold or wearing parts changing.
Mold Making Process
For those companies who had their injection mold making project proceed in China which is far away from their countries, deep understanding of the actual process of mold manufacturing is an advantage to get the project under tight control, sitting in the office and simply wait for a final result from the mold making company is always not a good way to go, It would be too late to do anything if don't manage your project step by step.
A mold project includes design, steel preparation, rough machine, precision machine, fitting and mold trail.
1) CAD design
The design is started with a 2d layout, basic mold design information will be present, such as mold size, gating way, parting line, ejection way, cavities layout, mechanical design, accessories used, steel of each component used, etc. 3D design in details and NC programming will follow after the 2d design is approved by the customer. Depends on the complexity, a complete mold design would need 3-7 days. Some of the complex projects require mold flow analysis or frequent updates of custom design, it could take much more time.
2) Mold base, steel and accessories preparation
Mold base and steel can be ordered immediately after design get confirm, accessories especially hot runner system could take much longer time to get back, all of this procedure need to be track closely if you don't want to cause any delay on next step.
3) Rough machine
The steel need first to be sized, milling, drilling, lather are the main process way to get the rough shape or the cavity /core. Normally 0.15-0.3 mm steel left for precision machining later.
4) Heat treatment
After rough machining, internal stress would be created during machining, do heat treatment to get certain hardness and internal balance, such as 1.2343, 1.2344, it usually need to be harden to HRC40+, some of the steel don't need it, like P20, 1.2312 etc.
5) CNC precision machining
To get designed dimension, the CNC process of precision machining is much slower than rough machining, also the steel hardness is much higher.
6) Wire cut and EDM
Wire cut is a process specially for holes (ejector pin holes, lifters, inserts), EDM is particularly for some of the area that can't not be machined by normal way, either too small to allow the cutting tool work properly, or it's too narrow to get there.
7) Finish and fitting
After all the components are finished and prepared, mold maker collects them all and assemble them by following the design drawing, it's a job rely heavily on experiences and skills, some of the part might need to be polished to fit, or the core or cavity have specially requirement for surface finish, such as texture, polish, engraving.
8) Mold trial
Congratulation if it's still on schedule as planning, it's the time to get the mold on an injection molding machine to do the trial. Make sure you made your requirement clear how many plastic parts you need for samples, instruct the mold making company to use the right resin, injection parameter and measurement report should be provided along with molded plastic parts.
