8 Best Precision Tooling Manufacturers in Selangor

Selangor’s tooling ecosystem runs along two physical corridors: the Shah Alam–Klang axis (heavy on automotive stamping dies and injection molds) and the Puchong–Bangi belt (faster-turnaround electronics tooling). These eight operations were selected on the basis of their in-house machining capacity, calibration practices, and the industries they currently invoice.

1. Pematech Precision Engineering Sdn Bhd

Pematech operates out of Section 28, Shah Alam, a strip packed with mold base suppliers and surface treatment shops. The company runs 14 machines including Makino V90 5-axis machining centers and a pair of Sodick Wire-cut EDM units with 0.5-micron resolution. They cut mostly SKD11, S136, and NAK80 for Class 102 plastic injection molds. Typical lead time for a glove-box latch mold is 42 to 48 days, including in-house electrode milling and deburring.

They maintain a Mitutoyo CMM with a stated uncertainty of 2.5 microns and calibrate it on an 18-month cycle via TUV SUD. Customers are mostly Tier 2 automotive suppliers in Puchong and Serendah. The shop floor runs two 9-hour shifts, six days a week, and they re-certify heat-treated tool steel through a partner furnace in Klang rather than handling quenching in-house.

2. Hamni Precision Sdn Bhd

Hamni Precision is a Korean–owned stamping die shop near i-City, Shah Alam. Their core output is progressive dies for connector terminals, busbars, and EMI shield cans. The floor is dominated by AgieCharmilles CUT 2000 wire EDMs and surface grinders holding flatness at 0.002 mm across a 300-mm face. They maintain their own die tryout press line with 60-ton and 110-ton presses up to 400 SPM.

The shop is IATF 16949 certified and supplies directly to Korean Tier 1 automotive module suppliers located in the Serendah and Rawang industrial areas. A typical progressive die for a 64-position board-to-board connector takes 9 to 11 weeks. They also run a separate cleanroom-adjacent assembly cell for fineblanked parts that have to be deburred and washed before shipment.

3. Okada Precision (M) Sdn Bhd

Okada Precision is a Japanese-affiliated toolroom in Bukit Raja, Klang that avoids conventional milling in favor of jig grinding and OD/ID grinding. The shop focuses on die components for semiconductor lead frames, including punch retainers and stripper plates. They run a Mitsui Seiki jig borer, which gives them hole patterns at +/- 2 microns over a 400-mm travel.

All grinding wheels are dressed in-house from Vitrified bond stock, and coolant filtration is set to 3 microns to prevent chatter on hardened A2 and D2 steels. This shop is clockwork-reliable for tight-tolerance plate work, and the typical job card involves 3 to 4 setups on the jig borer alone. Their clients in the Klang Valley include semiconductor subcontractors who need punch and die sets for SOIC and QFN lead frames.

4. Hi-Tech Tool & Die Sdn Bhd

Located along Jalan Tandang in Puchong, Hi-Tech Tool & Die is a mid-volume injection mold shop serving consumer electronics brands with quarterly design refreshes. Their machine floor includes 18 CNCs, mostly Fanuc Robodrill verticals and Mitsubishi wire-cut machines. The mold trial room has a 150-ton Engel machine, so most molds are sampled, measured, and approved before the tool ever leaves the building.

They specialize in thin-wall molding for earbud shells and battery housings, achieving wall sections at 0.6 mm. Hi-Tech also does in-house mold flow analysis using Modflow SVP and publishes actual cycle-time improvement reports for every set of changes they make. That documentation habit is what gets them repeat work from EMS (electronics manufacturing services) assemblers in Penang and Johor.

5. Vanguard Precision Metal Sdn Bhd

Vanguard sits in Bandar Baru Bangi, running a Feintool fineblanking press with 320 tons of force. Fineblanking gives them a smooth, fracture-free cut face, which matters for medical parts like scalpel handles and surgical stapler components. They produce their own fineblanking dies in-house, and the tooling team handles die sharpening every 40,000 to 60,000 strokes.

The ancillary operations include secondary CNC milling, surface grinding, and a 12-station vibratory deburring line. Vanguard’s quality lab has a profile projector and a Keyence digital measuring scope for verifying the stamped profiles at 20x and 50x magnification. The company ships internationally under ISO 13485, which is rare for a stamping shop in the southern Klang Valley.

6. Mylek Precision Engineering

Mylek Precision, in Selayang, serves the PET packaging sector. Their specialty is neck molds and blow molds for Sidel and Husky preform systems. The tooling is machined on a pair of 4-axis CNC lathes with live tooling and a 5-axis DMG MORI machining center. They also run EDM drilling machines to cut conformal cooling channels, which reduce cycle times in blow molding by allowing more aggressive water flow near the neck ring.

The shop cuts mostly beryllium-copper (BeCu) alloy and 17-4 PH stainless. Mylek keeps a stock of common neck finish sizes—28 mm, 29 mm, and 38 mm—so contract tooling jobs can start immediately. Heat treatment is outsourced to a vacuum furnace specialist in Rawang, and the shop performs all dimensional inspection in-house with a horizontal-arm CMM.

7. Starlight Precision Tooling

Starlight operates in Petaling Jaya and is deliberately positioned as a repair and maintenance toolroom rather than a new-build shop. They handle mold refurbishment, hot runner repair, and emergency tool swap-outs for manufacturers in the Dataran Glomac and Kelana Jaya industrial areas. The workbench floor includes three CNC milling machines, a sinker EDM, and a laser welding station for crack repair on hardened tool steel.

They have a hot runner bench tested against Mold-Masters and Synventive manifolds, and they keep gaskets, heater coils, and thermocouples for most 32-cavity cosmetic cap molds. A weekend emergency call-out for a stalled injection mold at a Plc manufacturer in Klang costs RM 1,800, including first-pull diagnosis and a written repair scope. That type of defined-pricing repair work is what keeps their floor booked.

8. Apex Mould Works Sdn Bhd

Apex Mould Works, in Kuala Langat, specializes in large-format automotive molds: bumpers, instrument panels, and tailgate trims. Their machining envelope reaches 3.2 m by 2.5 m, handled on a gantry-type machining center with a 36-ton table capacity. The shop is equipped with a portal CMM to verify surfaces and a 1,300-ton injection molding machine for full trial shots.

Tool steel for these molds is normally P20 and 738, sourced pre-hardened, then machined and textured via a contracted laser texturing shop in Shah Alam. Apex manages complete bumper mold programs, including gas-assisted injection channels and slide mechanisms, with an average program runtime of 16 weeks. Their quality gate is tied to the customer’s PPAP, not internal norms, which is exactly what local OEM suppliers need.
