Mould Precision Co., Ltd. is has Mold Build Standard itself, knows wells with SPI Mold Specifications and make mold meet to customers' Requie Specifications.

MP Mold Build Standard

A-Series LKM Standard Mold Bases, S50C Steel (18-22R/C)

Cavity & Core Machined in P-20 Steel Inserts (30-32 R/C) [However, some of the molds we build utilize hardened H-13, S-7, or 420SS (48-58 R/C). We try to recommend core & cavity materials based upon what we know about the project - part material, production amounts, life of the program, cycle requirements, expected maintenance, etc.]

SPI #3 Cavity Finish

Water/Cooling lines in Cores and Cavities (and in sub-inserts & slide bodies if feasible) with Jiffy-Plug connectors.

Guided Ejection system with Spring Loaded Return & Tapped Knock-out holes

Slides have: Hardened Heel Blocks, and Slide Retainers

Lifters typically have a Core and a separate lifting rods, Lifter guide bushings, and replaceable gib/couplings

Tunnel (sub) gate if possible (Edge/Chisel gate if Tunnel gate is not feasible) &Eyebolt holes in All Plates and Pry Slots

All Parting lines are either ground or hand blue fit NOT swedged down with fit press tonnage

All Vents are machine cut or machine ground NOT done by hand grinding

Hot Runner Systems are China Brand OR purchased from a recomended hot runner supplier.

Mold is stamped with Customer Name, Part Name, Part Number, Approximate Weight, and Manufacture Date. Inserts and Details are stamped with Material type and Detail Number. "0" corner is stamped in all mold plates.

If Plating is needed for wear resistance, corrosion resistance, or lubricity/release we typically use Armoloy (a pure chromium plating)

We are careful NOT to use like-steels on details that wear against each other and typically observe the rule of having 10 points R/C hardness difference as well as using good shutoff angles.

We are mindful of vulnerable shapes and high wear areas and we try to sub-insert these portions when feasible

Also, we try to recommend Parting Line Locks, Switches, Early Ejector Return Systems, Accelerated Ejectors, as well as other components and peripherals when we believe they are necessary.

Our average build would probably be considered a Class 103. Although we specialize in Class 101, 102, & 103 molds we do still build class 104 & 105 class preproduction
