HPAI equips with 21 sets injection machines from 50T to 1,200T for the mold tryout and volume production. We can outsource the 1,000T 2K injection machine and 2,500T single-shot injection machine in one hour’s driving way. We can provide the full dimensional inspection report, tryout parameter report, part samples, and long-time continuous production and tool testing video etc based on the customer request. HPAI is an ISO certified factory, and all tools are built to the APQP standards, plus using German and Japanese steels, all components have to be closely inspected in climate controlled environments prior to mold assembly to ensure the highest level of accuracy in every tool we built. Our rigorous mold testing includes complete 1st article inspection report per customer supplied part drawing. In additional we can supply full capability studies to include dimensional PPAP report and Gage R&R testing. Upon the completion of sampling and part approval, each tool goes through a 100% final inspection before delivery.
Classifications of Plastic Injection Molds
The following mold classifications are used by the Society of the Plastics Industry to define various standards of injection mold construction and the corresponding life expectancy.
SPI Class 102 Mold:- (Lifetime: One million or More)
DESCRIPTION: Built for extremely high production. This is the highest priced mold and is made with only the highest quality materials. Detailed mold design required.
1:- Mold base to be a minimum hardness of 28 R/C.
2:- Molding surfaces (cavities and cores) must be hardened to a minimum 48 R/C range. All other details, such as slides, heel blocks, gibs, wedge blocks, etc. should also be of hardened tool steels.
3:- Ejection should be guide 4:-Slides must have wear plates.
5:-Temperature control provisions to be in cavities, cores, and slides cores whenever possible.
6:- Electroless nickel plating of all water channels is recommended. This greatly inhibits the chance of rust and makes it easy to clear sediment from plugged lines.
7:- Parting line locks are required on all models.
SPI Class 102 Mold:- (Lifetime: Under one million)
DESCRIPTION: Medium to high production mold, good for abrasive materials and/or parts requiring close tolerances. This is a high quality, fairly high priced mold. Detailed mold design recommended.
1:- Mold base to be a minimum hardness of 28 R/C.
2:- Molding surfaces should be hardened to at least 48 R/C. All other functional details should be made and heat treated likewise.
3:- Temperature control provisions to be directly in the cavities, cores, and slide cores wherever possible.
4:- Parting line locks are recommended for all molds.
5:- The following items may or may not be required depending on the ultimate production quantities anticipated.
It is recommended that those items desired be checked and made a firm requirement for quoting purposes: Guided Ejection , Slide Wear Plates , Plated Temperature Control Channel Plated Cavities
SPI Class 103 Mold:- (Lifetime: Under 500,000)
DESCRIPTION: Medium production mold. This is a very popular mold for low to medium production needs. Most common price range. Detailed mold design recommended.
1:- Mold base must be minimum hardness of 8 R/C. 2:- Cavity and cores must be 28 R/C or higher. 3:- All other extras are optional.
SPI Class 104 Mold:- (Lifetime: Under 100,000)
DESCRIPTION: Low production mold. Used for limited production preferably with non abrasive materials. Low to moderate price range. Mold design recommended.
1:- Mold base can be of mild steel or aluminum. 2:- Cavities can be of aluminum, mild steel or any other agreed upon metal 3:- All other extras are optional.
